Barcelona defender Adriano Correia was undergoing a Besiktas medical yesterday.
Sport says although the transfer is not yet official, details have emerged about the move for the 31-year-old that will see him end his six-year spell at the Camp Nou.
The former Sevilla defender will sign a three-year contract and receive a salary of around €2.4 million net per season.
Although a transfer request was initially requested by Barça - with the player under contract until June 2017 - sources close to Besiktas claim that the Turkish club have finalised the deal for just €600,000.
