Besiktas are closing on a deal for Barcelona defender Adriano Correia.
NTVSpor says an agreement in principle has been reached between the player and the Turkish side.
The publication states that representatives of Besiktas met the player in the Catalan capital early this week.
However, there is an obstacle that is proving to be problematic for a deal to be finalised.
The 31-year-old Adriano exercised his option to automatically renew his Barcelona deal for one more season last March.
