The Catalan boss has stressed that there is still much to do against his team's eternal rivals, and has stressed that the Blaugrana must now concentrate on their Liga obligations
Speaking to journalists after the match, he said: "We knew we had to score, but the tie isn't over - Madrid always keep on fighting. Now focus on league game in 4 days."
The match was shrouded in controversy, mostly surrounding Real Madrid's Pepe, who arguably should have been sent off after a series of strong challenges and off the ball incidents. Guardiola, however, refused to comment on the situation.
"Pepe? Players talked about it, but I didn't see what happened. It seems it was clear on television."
The Portuguese had appeared to stamp on the hand of Lionel Messi, but the referee did not see the incident, leaving Blaugrana players incensed.
Barca return to La Liga action this weekend with a home game against Malaga, while Madrid travel to Athletic Bilbao.
