AC Milan have announced the signing of midfielder Jose Sosa from Besiktas to a three-year deal.
The 31-year-old former Napoli and Atletico Madrid man moves to the San Siro for a reported fee of €7.5 million.
A former Argentina international, Sosa made 31 Super Lig appearances for the Turkish side last season, scoring seven goals.
Sosa joins Gustavo Gomez, Gianluca Lapadula and Leonel Vangioni on Milan's list of new signings this summer.
He watched from the bench in Besiktas' penalty-shootout defeat in the Turkish Cup against Galatasaray last Saturday. It was his final game with the club.
