Chelsea boss Jose Mourinho insists he wants goalkeeper Petr Cech to stay at Stamford Bridge but admits the 32-year-old could decide to leave during next summer's transfer window.
The Czech international was in goal for Chelsea's Capital One Cup victory over Tottenham Hotspur on Sunday but failed to secure regular first team football in the Premier League.
But Mourinho has warned any clubs interested in signing the goalkeeper that they will have to make a high offer if they are to be taken seriously.
"He will make his decision," Mourinho said on Tuesday.
"He's very mature to make what he feels is the best decision for him and the best decision for his future.
"I will just wait. I would like him very much to stay. I don't waste my time trying to persuade him, because I know nobody can persuade him.
"If he tells me he wants to leave, I will tell him my opinion and my opinion is [that Cech is] one of the three best goalkeepers in the world. Huge money."
