Chelsea manager Jose Mourino says it will take "huge money" to prise Petr Cech away from Chelsea.
The goalkeeper joined the club from Rennes in 2004, and has since won 12 major titles including the Premier League three times and one Champions League crown.
This season has seen Cech usurped as Chelsea's first-choice keeper by Thibaut Courtois - with the former only making five league appearances this season - but Mourinho is not prepared to sell him on the cheap.
"He will make his decision," Mourinho told reporters. "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."
