Besiktas are reportedly interested in re-signing striker Cenk Tosun from Everton before the January transfer window closes.
Tosun, 29, moved to Goodison Park from the Turkish club in a £27million deal in January 2018 but has failed to hold down a regular starting place under successive Everton managers.
He has played just 164 minutes of football this season, making five substitute appearances in the Premier League and starting only against Championship side Rotherham United in the FA Cup third round, a game in which he scored.
Sky Sports report that Besiktas are keen to re-sign Tosun, who scored 64 goals in 142 appearances for the club between 2014 and 2018, while there is also interest from Russian club CSKA Moscow.
