The Blaugrana face their arch-rivals Real Madrid at Camp Nou.
Barcelona managed to beat Panathinaikos 3-0 on Wednesday evening in the Champions League.
“We hope to follow this by winning el clasico because that is important,” the defensive midfielder told Barca’s official website.
“But it is three points and we cannot drive ourselves mad. We should intend to remain calm. The game is on Monday and not before.”
