Chelsea are reportedly planning to offer out-of-favour striker Demba Ba to Galatasaray as part of a deal to land Burak Yilmaz in January.
Blues manager Jose Mourinho is believed to be an admirer of the 28-year-old Turkish international, who has scored 96 goals in 183 matches in the Super Lig.
According to Eurosport Turkey, the 50-year-old was put off by Gala's reported £20m valuation during the summer transfer window, but hopes that giving the Senegalese striker in return will knock the price down.
The 28-year-old joined Chelsea from Newcastle United in January but does not seem to feature in the new manager's plans at Stamford Bridge, having started just two Premier League games this season.
A loan move to Arsenal nearly materialised on transfer deadline day, only for him to be denied the opportunity at the end when the Blues allowed Romelu Lukaku to join Everton for the season instead.
