Real Madrid defender Sergio Ramos admits victory tonight at Barcelona will hurt their championship ambitions.

"Although I never would write-off Barcelona, because there's still a long way to go this season, there's no doubt if we win at the Nou Camp it would be a huge blow for them," said Ramos.

"Both teams are fighting for the championship, but there's no doubt that if Barca were to lose at home, it would hurt them much more."
