Real Madrid captain Iker Casillas denies tension with Cristiano Ronaldo.

Real's dressing room is said to be split between the two heavyweights.

But Casillas insists: "Whether I celebrate goals or not has nothing to do with Cristiano. There are times when letting in a goal hurts you as a goalkeeper and I am very strict with myself. At other times I have celebrated them. The good things that happen to Cristiano are also good things for Real Madrid."
