Former Real Madrid president Ramon Calderon has stated his belief that Jose Mourinho has already decided to leave the club next summer.

Mourinho, 49, has been in charge at the Bernabeu since 2010 and during that time he has managed to end Barcelona's domestic dominance by winning both the La Liga title and the Copa del Rey.

However, Calderon believes that the Portuguese coach has become "fed up" with life in Spain.

"I think he has already decided to leave," he told BBC Radio Five Live. "That's my opinion and I'm not certain about that.

"He's a bit fed up with what's happening here and some people are fed up with his attitude and his behaviour. It is my opinion that he will leave at the end of this season."

Mourinho's side are currently in England for a Champions League encounter with Manchester City this evening.
