Long-serving goalkeeper Petr Cech could reportedly leave Chelsea for Besiktas at the end of the season.
The Czech Republic international has been ousted as the Blues' number one following the return of Thibaut Courtois from his loan spells at Atletico Madrid.
Cech has made just four starts for Chelsea so far this season and has admitted that he may look for a new club if he continues to sit on the bench.
Reports in Turkey have suggested that Besiktas will offer the 32-year-old a contract next summer which will guarantee him first-team football.
Cech has made 327 appearances for Chelsea since signing for the club from Rennes in 2004.
