Besiktas are in talks with former Everton striker Oumar Niasse.
Niasse is currently a free agent and training on his own as he seeks his next move.
Niasse's minders are in talks with Besiktas about a contract, with terms close to being settled. However, Fanatik says coach Sergen Yalcin is yet to make a final call on his signing.
A decision is expected from Yalcin this week.
Niasse was allowed to come off contract at Everton over the summer.
