Barcelona have confirmed full-back Adriano Correia is set to join Besiktas after an agreement was reached between the two clubs.
The 31-year-old moves to Istanbul for a fee of €600,000, though that could rise to €2.3 million if Besiktas qualify for the Champions League while Adriano is with the club.
Brazil international Adriano made 189 appearances for the Camp Nou outfit, scoring 17 goals, and played his part in the Blaugrana
winning 16 trophies during his time with the club.
He becomes the second full-back to leave the club this summer after Dani Alves joined Juventus on a free transfer.
