Real Madrid defender Sergio Ramos is at a loss to explain Barcelona's superiority after last night's Copa defeat.

Eric Abidal proved an unlikely matchwinner as Barcelona came from behind to beat Real.

Ramos lamented in the mixed zone: "It will be difficult to defeat Barcelona at the Camp Nou, but we're not about to give the Copa away. I can't possibly say what we lack to defeat them. You sometimes win and others you lose. It hurts because they are our main opponent. It's difficult but not impossible.

"We adapted to our manager's philosophy. Mentality and attitude are what matters. Bets are won and lost. We have yet to play the return leg and anything can happen. We must have a winning mentality at the Camp Nou.

"There aren't going to be any more tense moments or discussions between both teams. There were more things at stake in previous seasons, such as a title. These images tarnish football and they're not worth people's time."
