Real Madrid goalkeeper Iker Casillas has said that he and his teammates are determined to win against Barcelona in La Liga on Saturday.

The two Spanish rivals will face each other in the first El Clasico of the season at Camp Nou, with Barca leading Los Blancos by three points.

"We have to take advantage of what happened in the last matchday," Madrid's official website quotes him as saying.

"A win would put us joint-first, depending on what Atletico Madrid do. We have to go with the idea of winning the match and playing good football."

Barcelona dropped their first points in La Liga this season last weekend as they were held to a goalless draw by Osasuna in Pamplona.
