Manuel Pellegrini has stated that Real Madrid will be looking to take the initiative at the Nou Camp, and attack Barcelona from the start.

"We are going to the Camp Nou to attack," he declared to Marca.

"We will use our weapons, which are different to those of Barcelona, but they are as good as theirs."

The Chilean is confident that Los Blancos are as good as La Blaugrana, and Real will try to prove that on Sunday.

"Barca are a great team, they aren't just Xavi, [Andres] Iniesta and [Lionel] Messi. Pep Guardiola's side plays good football and have a lot of quality, but they are not superior to us. We won't go out for the draw against Barca. We know what we have to do in the Camp Nou."

Pellegrini revealed that he has been thinking about El Clasico for the whole week and is optimistic that Cristiano Ronaldo will be able to play for as long as possible.

"We have spent all week planning our strategy. Real Madrid are playing well, not for 90 minutes, but we are playing good matches.

"There isn't a set amount of time that Cristiano can play for in the Camp Nou. We will see how long he plays for. The Portuguese is an irreplaceable player."
