Chelsea have approached Galatasaray about the availability of Burak Yilmaz.
The Guardian says Chelsea, who should confirm the reappointment of José Mourinho as manager by the middle of next month, contacted Galatasaray to discover whether the 27-year-old was available.
They were informed it would take a bid in excess of £20m to prise away the forward, who signed a four-year deal with an option for a further season when joining from Trabzonspor last summer.
