Besiktas have completed the signing of Adriano Correia from Barcelona for an initial €600,000.
Barcelona said the transfer fee for Adriano, 31, will rise by €1.7 million if Bestikas qualify for the Champions League within the duration of his contract.
He was previously reported to have agreed a three-year deal.
The Turkish club confirmed at the weekend that negotiations to sign the Brazilian full-back were underway and he has now completed the move.
