Petr Cech says new Manchester City signing Robinho will regret not making the move to Chelsea.

"In the morning he says he loves Chelsea and he wants to be part of Chelsea and a few hours later he signs for another club," Cech told Sky Sports News.

"It was his decision. He needs to play well for Manchester City and we want to show him on Saturday he made a decision that is not perfect for him really."

But Cech believes Robinho could be a success in the Premier League.

"He is a great player and the sort of player who can entertain people so for the Premier League maybe he is good, but we will see how he is going to cope with the pressure now," added Cech.
