Mateo Retegui has joined Genoa from Boca Juniors, the newly-promoted Serie A side said on Wednesday.
Genoa announced the transfer on social media with the striker depicted on a playing card and the message "Retegui, a new king in town".
Italy forward Retegui has signed a four-year contract after moving to Italy from his native Argentina for a reported fee of 12 million euros ($13.3 million).
Previously on loan from Boca at Tigre, Retegui signs for Genoa after impressing for Italy following a surprise call up by Roberto Mancini last season in a bid to end the Azzurri's striker problem.
The 24-year-old scored twice, against England and Malta, in his first three matches after opting to play for Italy earlier this year.
Genoa are back in Serie A after earning automatic promotion last season, and begin their campaign with the visit of Fiorentina on August 19.
