Guardiola said everyone at the club would "enjoy the result for a few days", but the Catalans' attentions now turns to the game at Osasuna.
Midfielder Jeffren Suarez, who came on as a late substitute to score the fifth goal for Barca on Monday, says all talk of the 'Clasico' has been banished from the dressing room.
"He (Guardiola) has told us to forget about it because we have a difficult match at Osasuna on Saturday," he said.
Jeffren is confident his side can match the level they showed against Madrid on a regular basis.
"It was a great performance and for me personally it was a great feeling to score in a 'Clasico', but now we have to keep it up," he said.
"This team is always anxious to win, though, and there will be more performances like that."
