Midfielder Romeo Lavia will undergo a medical on Wednesday ahead of his move to Chelsea, while Hakim Ziyech is close to exiting Stamford Bridge. The Blues agreed an initial £53million fee to sign Lavia from Southampton on Tuesday, which could rise to £58m in add-ons, the PA news agency understands. Lavia is now in London to go through his medical tests but Ziyech will be the latest player to go through the exit door at Chelsea after an agreement in principle was reached with Galatasaray for his transfer. It has been a whirlwind few days for Mauricio Pochettino’s team, with the British record capture of Moises Caicedo from Brighton completed on Monday. Caicedo’s transfer could eventually total £115m and a day later the Blues closed in on the signings of Lavia and Crystal Palace winger Michael Olise. After Lavia made it known to Southampton on Monday that he favoured a move to west London, Chelsea and the recently-relegated Saints reached an agreement for his transfer on Tuesday night. Lavia will sign for an initial £53m with Southampton able to receive a further £5m in add-ons. The spending under owner Todd Boehly shows no sign of slowing down though, with Olise’s £35m release clause activated on Tuesday, PA understands. It allows Chelsea to now negotiate personal terms with the highly-rated Crystal Palace winger. Olise is currently out injured with a hamstring issue and his current club Palace are reported to be unhappy with Chelsea’s conduct during their pursuit of the France Under-21 international. PA understands Chelsea are comfortable they have done nothing untoward and Olise is expected to finalise his move this week. Ziyech should leave after Chelsea and Galatasaray reached an agreement for his transfer on Wednesday, but the Morocco forward still has a medical to complete after moves to Paris St Germain and Al Nassr collapsed earlier this year.

Chelsea are set to take their spending under Todd Boehly to a whopping £1billion if they can get deals for Romeo Lavia and Michael Olise over the line. The American has splashed the cash since taking over at Stamford Bridge, backing Thomas Tuchel, Graham Potter and Mauricio Pochettino heavily in the transfer market. Here, the PA news agency takes a look at the biggest deals. Moses Caicedo (£115million) The Blues beat off competition from Liverpool for the signature of the highly-rated Brighton midfielder, who is the third most expensive under-21 player in the world behind Kylian Mbappe and Joao Felix. They paid £100m up front, but that could rise to £115m depending on certain criteria. Enzo Fernandez (£106.8m) Chelsea smashed the British transfer record when they signed the World Cup winner from Benfica in the January transfer window for an outright £106m, surpassing Jack Grealish’s fee for his move from Aston Villa to Manchester City. Mykhailo Mudryk (£88.5m) The Ukraine star cost £62million up front when he joined from Shakhtar Donetsk in January, but that fee could rise to £88.5m with possible add-ons. Wesley Fofana (£75m) Chelsea were after defensive reinforcements when they signed Wesley Fofana from Leicester. The France international cost £70million, with a possible further £5m to be paid to the Foxes in add-ons. Marc Cucurella (£63m) Chelsea have looked to Brighton on a number of occasions and, a few months before Graham Potter made the move from the Amex, the Blues signed left-back Cucurella for £56m, with a further £7m due in extras.

Liverpool are stepping up their efforts to sign Crystal Palace midfielder Cheick Doucoure. Jurgen Klopp has insisted on a number six to bolster his squad after missing out on Moises Caicedo to Chelsea, with Romeo Lavia set to follow the Ecuadorian to Stamford Bridge. The Anfield club have had to search for alternative options, with Doucoure likely to be cheaper than both previous targets. Doucoure’s final price could come in at under £60 million, although Palace are wary of losing too many players this summer. The Malian midfielder is understood to be keen to move to Anfield, and personal terms would not be an issue. Liverpool are also looking at Fulham's Joao Paulinha and Nice's Khephren Thuram but the 23-year-old Doucoure is seen as a more viable option to do right now. Klopp is keen to “reload” in the coming weeks as the Reds revamp their squad and starting options. The German said: “We don’t have to always say ‘Milner would have said that and Henderson would have said that and Firmino would have smiled here.’ We should not do it like that. That makes no sense. “We have this kind of new start with this Liverpool reloaded, it’s an exciting thing. Everybody was asking for changes, rightly so, because we were together for a long time. “It’s a new chance for everybody, everybody has to step up. We all share responsibility and it’s not that we should give ourselves too much time to grow into it, let’s do it. “Let’s take the responsibility and go from there and don’t try to be like somebody. Be the best version of yourself and then you have a good chance to help the team in the best possible way.” Read More Big-spending Chelsea close to completing deals for Romeo Lavia and Michael Olise Moises Caicedo completes Chelsea’s dream midfield — but £115m deal could haunt them Chelsea-Liverpool chaos was the perfect result for one team: Brighton

Harry Maguire’s £30 million move to West Ham is off, with the England defender now likely to stay at Manchester United. The two clubs had agreed a fee for the centre back, who had been stripped of the Man United captaincy this summer. But Maguire would have had to take a substantial cut in his wages to leave Old Trafford, with his Man United salary going up this summer after Erik ten Hag’s team qualified for the Champions League, and no pay-off was agreed. Ten Hag has always said that he regards Maguire as a valuable member of his squad and wanted the former Leicester, Hull and Sheffield United player to stay and fight for his place. He was on the bench for Monday’s 1-0 win over Wolves, though Ten Hag brought on Victor Lindelof ahead of him. Man United were also concerned that Maguire’s departure this late in the window would not have given them much time to find a replacement, though Bayern Munich’s Benjamin Pavard would have been one contender. West Ham, who have signed midfielders Edson Alvarez and James Ward-Prowse with the proceeds of Declan Rice’s £105million sale to Arsenal, are now expected to switch their attention to other defensive targets. The former Man United midfielder Jesse Lingard, who had a successful loan spell under David Moyes in 2021/22, is also training with West Ham and available on a free transfer after leaving Nottingham Forest.

Watch live as supporters arrive at Stadium Australia for the Women’s World Cup semi-final between Australia and England. A place in the showpiece final is up for grabs, in what could be one of the biggest football matches of the year so far. For Australia, they will hope star striker Sam Kerr will be fit enough to feature from the start. She picked up an injury ahead of the tournament and has been limited to appearing as a substitute so far. England boss Sarina Wiegman, though, believes simply nullifying the threat posed by Kerr will not be enough to see the Lionesses through to a first-ever World Cup final. The Australia captain is her country’s leading goal-scorer of either gender but has not yet started a match in the global showpiece after injuring her calf. European champions England take on the Matildas at 11am BST in Sydney, where the majority of the 75,000 in attendance will be backing the co-hosts.

England face hosts Australia in the Women’s World Cup semi-finals as the Lionesses come up against not just the Matildas but an entire nation in Sydney. The stage for the latest chapter of England and Australia’s historic rivalry could not be bigger as both teams aim to reach their first-ever Women’s World Cup final, with the hosts gripped by Matildas fever and set for their biggest sporting occasion since the 2000 Olympic Games. The Lionesses rode the wave of home support as they won the Euros last summer but will now look to spoil the party as Sarina Wiegman’s side attempt to make history of their own. England have overcome several challenges to reach the semi-finals and are now faced with their biggest yet as they take on a near-80,000 capacity crowd at Stadium Australia.

England’s Rachel Daly is one of six World Cup stars who have been shortlisted for the Professional Footballers’ Association Players’ Player of the Year award. Forward Daly hit 22 goals in the Women’s Super League for Aston Villa last season – a remarkable achievement for a player who featured at left-back in the Lionesses’ successful Euros campaign last summer. Her form last season has made her a first choice up front at the World Cup for England manager Sarina Wiegman. The 31-year-old from Harrogate is joined by five other illustrious WSL names on the nominees list, including Australia striker Sam Kerr, Norwegian duo Frida Maanum and Guro Reiten, Khadija ‘Bunny’ Shaw and Spain’s Ona Batlle. Kerr and Reiten were key components of a Chelsea team which secured a sixth WSL title last season, with Kerr scoring the winner as the Blues claimed the domestic double with victory over Manchester United in the FA Cup final. Reiten’s international team-mate Maanum was a major asset to Arsenal last term. Her versatility in midfield has made her a vital part of Jonas Eidevall’s Gunners team since her arrival from Linkoping in July 2021. Full-back Batlle was part of a Manchester United squad which pushed Chelsea close in the league all season and helped the team qualify for the Champions League for the first time in their history. She returned to Barcelona earlier this summer when her United contract expired. Shaw was a shining light in what was a disappointing season on the whole for Manchester City, scoring 31 goals in 30 games in all competitions. Her performances earned her a contract extension through to 2026 earlier this summer.

Referee-turned-pundit Mike Dean says he will not have any issue in telling former colleague Simon Hooper how badly he got things wrong by not giving Wolves a penalty in their defeat at Manchester United on Monday. Hooper and VAR officials Michael Salisbury and Richard West have been stood down for this weekend by Professional Game Match Officials Limited (PGMOL) boss Howard Webb after they collectively failed to award Gary O’Neil’s side what looked like a blatant spot-kick in added time of the 1-0 loss at Old Trafford. Dean quit his role as a dedicated VAR and coach of up and coming officials in the summer in order to move into a role as a pundit on Sky Sports’ Soccer Saturday. And the 55-year-old, who made his debut on the show last week, has warned his former colleagues that he “won’t be sitting on the fence” when it comes to discussing controversial decisions. “I’ve had a chat with a few of the referees and made it clear that if they make a bad decision, I won’t be sitting on the fence or defending the indefensible and they were OK with that,” he told the PA news agency. “I want to be able to do the job properly and give proper insight. “Equally, I’ll be happy to highlight good decisions as it will be good to give refs some credit.” Dean was an on-field referee for 27 years – 22 of those in the Premier League – and was undoubtedly one of the biggest characters in the game, with his antics and exaggerated facial expressions prime content for online memes. His final year for the PGMOL was spent at Stockley Park as a dedicated VAR and he admits he did not get the same satisfaction. “For me refereeing was the best job in the world, and I felt lucky to be able to be paid for basically doing my hobby,” he said. “But after 27 years of refereeing, and 22 in the Premier League, I felt like I had done my time and wanted to start the next chapter of my life. “It didn’t take long for me to realise that being on VAR wasn’t for me. Having to travel down to London to then be stuck in a room, telling on-field referees whether their decisions were right or wrong didn’t give me the same enjoyment. “I spoke to Howard about this and luckily he supported me in my move away from the role. “I only ever tried to be the best referee I could be. I don’t shy away from the fact I did the job in a different way to some others, but this just came from my enjoyment of it. “I loved my career, seeing Premier League football every weekend from the best seat in the house. I got to referee some amazing games like Man City against QPR when they won the league in the last minute, and make some great mates.” Webb has had a tough induction to the top job at the PGMOL since taking over from Mike Riley in December but has been committed to making his officials accountable for their errors and also improved communication. Dean insists the former World Cup final official is the “best man for the job”. He added: “I have no doubt that Howard is the best man for the job, he has a real presence and is respected in the game. It didn’t take long for me to realise that being on VAR wasn’t for me Mike Dean “He’ll be in contact with Premier League managers this year and will have no problems being up front and honest with them – this communication should only help this season. “Premier League football and decisions in big games will always get attention, and it is the nature of being a referee that you will get criticised when you make mistakes just like players. “The difference for referees is that you will rarely get called out for refereeing a game well, or making good decisions. That’s why I’m not a fan of the idea of refs being interviewed after games, as they’d only want to be spoken to when they’ve made an error.” :: Mike Dean has a new role as the face of the Family & Friends Railcard. Research from Railcard.co.uk reveals that fans opting to travel by train to football matches can save over £50 per adult and child just by using the Family & Friends Railcard.

There is something so wonderfully comforting about a bowl of ramen noodles, whatever the season,” says chef and TV presenter Shivi Ramoutar, author of Cook Clever. “This version uses packet ramen – don’t turn your nose up at it; I assure you that with the added flavours, veg and protein, it becomes something spectacular and amazingly easy to accomplish. This is one to elevate to your heart’s content – you really can’t go too OTT with this. Have it slurpy or dry as you like.” Pimped packet ramen Serves: 2 Ingredients: For the base: 2 tbsp toasted sesame oil 1 spring onion (white bulb discarded), snipped 1 tsp garlic purée 2 mugs of boiling water 2 packets of ramen noodles (or any other instant noodles) OR 300g ready cooked noodles and 1 chicken stock cube, crumbled OR 300g ready cooked noodles and 2 sachets of miso soup mix For the protein (choose from): 1 mug of frozen, fresh or cooked chicken strips 1 mug of frozen, fresh or cooked seafood 1 mug of frozen or fresh gyoza dumplings ½ block of firm tofu, broken into smaller pieces For the veg: 250g packet of pak choi, leaves separated ½ mug of frozen vegetables Toppers (choose as many as you like): Soft-boiled egg halves Drizzles of chilli oil 1 tbsp sesame seeds Fresh coriander sprigs Fresh chillies Kimchi Drizzles of sriracha Method: 1. Heat the oil in a small saucepan over a medium heat and cook the spring onion and garlic purée for a couple minutes, stirring often until aromatic. 2. Add the boiling water, along with the dried noodles and their flavour sachets, or the cooked noodles with the crumbled stock cube or the miso soup sachets. Stir together and cook for a minute or two until the liquid is mostly absorbed. 3. Add your chosen protein and the veg and cook until the protein is just cooked through, about five minutes or so. If you are using fresh chicken or seafood it will take less time. If using tofu, add in the last few minutes so it doesn’t disintegrate. 4. Serve into bowls and go crazy with the toppers. ‘Cook Clever: One Chop, No Waste, All Taste’ by Shivi Ramoutar (HarperCollins, £20).

This is a versatile dish that you can pair with many different things; have it with rice, smother it over fries, put it on a hot dog, pour it over a jacket spud or just use it as a dip for tortilla chips,” says Mitch Lane, author of Feed Your Family For Under A Fiver. “It can be frozen as well, so it’s great for saving time while meal prepping! I use store-bought chilli con carne seasoning, but if you have a lot of spices in your cupboard (cumin, chilli powder, paprika, cumin seeds) then you’re on to a winner. This is so simple and it absolutely slaps with flavour.” Chilli con carne Serves: 4 Ingredients: 1 tsp vegetable or olive oil 1 onion, finely chopped 4 garlic cloves, finely chopped 2 green chillies, finely chopped, plus 1 to serve 500g minced beef 41g packet of chilli con carne seasoning 400g tin chopped tomatoes 130g tin kidney beans, drained 300ml beef stock (made with a stock cube) Salt and pepper Method: 1. Put a pan on a medium heat and add the oil and the onion and soften for three to four minutes. Add the garlic and chillies and continue to cook for a further two minutes. If you’re not keen on a lot of spice just use one chilli and remove the seeds. 2. Add the mince and break it up with the back of a spoon, ensuring that there’s no big lumps. Cook the meat until it’s nice and brown. Be generous with the salt and pepper and then add the chilli con carne seasoning. Mix well. 3. Add the tomatoes and kidney beans and stir. Then pour in the beef stock and simmer for 30 minutes. The simmering is very important (it’s like a fine wine that gets better with age). 4. Serve with sliced chilli. ‘Feed Your Family For Under A Fiver’ by Mitch Lane (Thorsons, £16.99).

As the cost-of-living crisis continues to bite, many of us are looking for ways to save money where we can. Food shops are one of the main things that have become more expensive in recent years – so are there any easy ways to save a bit of cash in the kitchen? Chefs are on hand to share their top money-saving tips… Make simple swaps Suzanne Mulholland, author of The Batch Lady: Cooking On A Budget (HQ, £22) recommends letting go of loyalty to brand names. For example, she says: “You’re not going to notice a difference in flour – yet it’s about a fifth of the price of a branded one.” Mulholland continues: “If you love to eat haddock, then buy hake instead. If you like to eat cod, buy coley instead – monkfish? Buy seacat. These are all very similar fishes, but they’re just not the most popular ones everybody else buys. “You wouldn’t actually notice the difference between eating a different type of fish, because hake is very much like haddock – yet because it’s not that popular, it’s half the price. It’s also locally sourced, because these are all British fish.” Maunika Gowardhan, author of Tandoori Home Cooking (Hardie Grant, £25), also advocates cost-effective swaps. “If it’s a chicken recipe, I normally use chicken thighs over chicken breasts,” she says. “It’s a cheaper cut of meat, and it’s a more flavourful cut of meat.” If you’re a keen baker, The Great British Bake Off’s Kim-Joy (Bake Me A Cat, Quadrille, £16.99) has a top tip for you. As butter “has become so much more expensive”, she recommends “using more vegetable oil in baking”. Make a plan “Most people are cooking blindly,” says chef Max La Manna (You Can Cook This!, Ebury Publishing, £22), “Pulling ingredients together and cooking – they do the same when they go to a supermarket, they buy ingredients – and a lot of waste happens when people don’t have a plan.” La Manna’s top tip is firstly “cook the food you already have before you go out and buy more”. After that, it’s all about making a plan. “Shop smarter,” says La Manna. “Create lists when you go to the supermarket, and stick to that list.” Make your ingredients last longer Throwing away produce that’s gone off is money down the drain – so La Manna is keen for us all to make ingredients last longer. “You can extend the shelf life of ingredients – for instance, most people throw away bag salad or herbs,” he says. “What I do with my bag salad, once I bring it home I’ll wash it and also let it sit in cold water – because it firms up and it gets crisp and it stays fresh a little longer.” Once he’s washed the salad, he divides the bag of leaves – putting half in a container in a tea towel (“to absorb some of the moisture”) and use within the next three or four days. “The other half I cook in hot water – blanch it really quickly, squeeze out the water, then I have this kind of pre-cooked spinach. Roll that up tightly, place it in the freezer and then when I need something in a week’s time – a stew, a soup, a curry, a stir-fry – pop those in.” You can also reduce waste by knowing how to store all your other produce properly. “That’s where a lot of waste is coming in, people put ingredients away, they turn their back and the food’s already gone bad,” says La Manna. “Know how to store your produce and where to store it – potatoes should be kept in a cupboard somewhere dry, dark, cool but well-ventilated so they don’t begin to sprout. Same thing with onions. Bananas like to have their own space – bananas don’t like to be with other ingredients, because they release a chemical and will ripen quicker.” Instead of throwing away bananas on the turn, La Manna says: “It’s great for the freezer, [or] use them in smoothies. Use them as a batter for cupcakes or cakes.” Use every part of your ingredients “With Chinese food, there really is a ‘no waste’ policy,” says Kwoklyn Wan (One Wok, One Pot, Quadrille, £16.99) – and he suggests this ethos could help you save money in the kitchen. “Even when you peel your onions, use the onion skin in the stock” – along with anything else you might normally throw away, such as the top ends of carrots or fish heads. “That’s so important – if people learn to use every part of that ingredient… You can have a fantastic dish with all the best bits, and at the end of it, you’ve got this fantastic soup base. All you’ve got to do is add really cheap noodles into it, and maybe a few veggies and tofu, some chicken – whatever. “You’ve got this lovely broth – and that’s your next meal completely free, or near enough.” Be smart with your ingredients Most of us are guilty of buying an exciting-sounding ingredient for our store cupboard and only using it once. If you really want to save money in the kitchen, it’s all about being smart with what you buy – and making sure you’re going to use it a lot. Lydia Vernon, co-author of Caught Snackin’ (Hamlyn, £20), says that on Caught Snackin’s wildly popular TikTok channel,”we like to keep with the same ingredients for each recipe. “We stay around things like mixed herbs, garlic powder, plain flour – those kind of staples you have in your cupboard all the time, which are going to be cost-effective.” Food writer Gurdeep Loyal (Mother Tongue, Fourth Estate, £26) takes this one step further, saying: “My advice would be to equip your pantry with four or five very flavour-forward ingredients – things such as tamarind paste, things such as brown miso, things such as fennel seeds, for example, or something like tandoori masala powder. “Because these four or five pantry staples can transform anything really simple and basic – just adding a spoonful of this is going to amplify your cooking into hundreds of different directions. “It means you can use very basic supermarket staples, then turn them into something incredible” – without having to spend money on fancy new ingredients every week.

This vibrantly green pasta recipe is one of my favourites in the book,” says Mimi Harrison, author of Beat The Budget. “Not only is it bright and Instagrammable, it’s also so delicious. The frozen spinach is reasonably priced and you don’t have to worry about it going off in the fridge. And the goat’s cheese provides creaminess, acidity and tang, all in one ingredient (hello, cost-effective!). “This is ideal for a speedy meal when you’re in a rush, or to serve to friends at a dinner party when you don’t want to spend half the night in the kitchen.” Goat’s cheese, spinach and basil linguine Serves: 5 Ingredients: 1 tbsp olive oil 1 onion, diced 500g linguine 3 garlic cloves, finely grated 160g frozen spinach 125g goat’s cheese 30g fresh basil Salt and pepper to taste Chilli flakes (optional) Method: 1. Set a non-stick pan over a medium heat and add the olive oil. Add the onion, season with salt and pepper and gently fry for four minutes. 2. Meanwhile, set a large pan of salted water over a medium heat and bring to a boil. Add the linguine and cook for two minutes less than the packet cooking time. 3. While the pasta is cooking and once the onions have softened, add the garlic to fry for a minute before adding the frozen spinach to the pan, along with 400 millilitres of the starchy pasta water. Increase the heat and cook the spinach and onion mix until the pasta is ready. 4. Add the spinach and onion mix to a blender with half of the goat’s cheese and the basil and blitz until smooth. 5. Drain the linguine and transfer back to the pan. Pour over the blended sauce and continue to cook over a low\medium heat. 6. After about two minutes, the sauce should thicken and coat the linguine. Serve with a sprinkle of any remaining goat’s cheese and a pinch of salt and pepper. Optionally, top with chilli flakes if you love a little heat. ‘Beat The Budget’ by Mimi Harrison (Ebury Press, £16.99).
