Real Madrid coach Jose Mourinho concedes the future of Kaka is up in the air. But despite confirmation of talks with AC Milan, Mourinho says Kaka may indeed stay with Real.

"I don't know if he will leave or not. Anything can happen," said Mourinho.

"It may also be that he remains in Madrid for next season. If that is so then I will be happy as we have a good relationship.

"Between us there are no secrets - he knows what I think and vice versa."
