Real Madrid star Cristiano Ronaldo admits he doesn't know if Jose Mourinho will stay as coach next season.

Mourinho has been linked with a return to Chelsea.

Asked if he knows what Mourinho will do once the season finishes, Ronaldo told AS: "I don't know. I think he will continue until the end of the season at least, because he's a coach who always wants to win and we have several challenges ahead which we can achieve.

"After that he will decide what's best for him, for his professional group and for the club. But I don't know what either he or the club thinks and therefore I prefer not to talk about this subject."
