Chelsea midfielder Jon Obi Mikel has suggested that he could leave the club amid reported interest from Galatasaray.
The Nigerian international has four years left on his current contract at Stamford Bridge.
However, Mikel believes that the unpredictability of the summer transfer window could see him move away from the Europa League winners.
"I have a four-year contract with Chelsea, but you know, in football you can never guess, one day you are here, the next day you might leave," the 26-year-old told Sky Sports News.
Mikel joined Chelsea from Lyn Oslo in 2005.
