Petr Cech's agent claims an unnamed club is prepared to make a 40 million euros (£30million) bid for the Chelsea goalkeeper.

The Czech Republic international is widely regarded as one of the best keepers in Europe following his exploits at Stamford Bridge.

Cech's agent Pavel Zika admits there is a long list of clubs interested in the giant custodian, but says it is unlikely Chelsea would be prepared to sell the keeper.

"I know a big European club which would be willing to pay 40 million euros [for Cech]," Zika told Czech daily Pravo.

"A few weeks ago a club director in charge of those kind of matters told me [of the interest].

"It is an unbelievable sum for a goalkeeper. I cannot name the club. They would have problems as even such an inquiry could be understood as a breach of rules.

"Some of the top ten European clubs have been probing our agency but I will not say which ones they are.

"Also their offers have been around 40 million euros."

Improved contract

Zika also revealed they will seek talks over an improved contract for Cech at the end of the season.

"I cannot speak for Chelsea, but I believe they are absolutely satisfied with Cech and vice versa.

"After the season we will be revising Petr's current contract and negotiate a raise."
