Barcelona coach Pep Guardiola refuses to talk up the importance of victory in the El Clasico.

Jose Mourinho's Real Madrid are three points ahead with a game in hand.

But Guardiola said: "Madrid are always strong. Tomorrow we begin to think, to see what we have to do.

"They have an impeccable track record, they are always good and this year too. I'll try to do my best."

He added: "Let's try to find the way to suffer the least amount possible and to attack in the best way possible."
