Barcelona also won on the day against Racing Santander, but Casillas says: "It is not a definitive blow, but I imagine that this will hurt a lot those that are immediately behind us.

"There's still a long way to go in the Liga and plenty of things can still happen."

Real captain Raul said: "It was our best performance of the season away from home. We also won important games at Valencia and Villarreal, but didn't play as well as we did today."
