Fenerbahce president Aziz Yildirim has confirmed that Chelsea are ready to sell midfielder John Obi Mikel for £25m.
The Nigeria international is one of four midfielders who could leave the club during the summer transfer window.
Oscar, Juan Cuadrado and Mohamed Salah have also attracted interest from a number of Serie A clubs although only Mikel and Salah are expected to leave Stamford Bridge this month.
Fenerbahce have already strengthened their midfield after signing Nani from Manchester United but are not ready to meet Chelsea's £25m price tag for the Nigerian.
