Chelsea boss Jose Mourinho says they'll demand a big fee should Petr Cech ask to leave.

The goalkeeper has been linked with Arsenal and Liverpool.

"If he tells me he wants to leave, then I'll give my opinion, and that is that he belongs in the three best goalkeepers in the world. So he will be very expensive," said Mourinho.

"Petr will make his own decision," continued the coach. "He is mature enough to know what is the best decision for him.

"I'd like him to stay, but I will not bother to convince him, because I know this does not make any sense. Nobody can convince him, he should make that decision himself."
