The match was highlighted by a hat-trick from Lionel Messi.
"The work put in by the entire team was enormous," Zubi said. "The names of Messi and Iniesta will always be remembered in football history. They played a great game.
Despite the magnitude of the victory, Zubi warned: "On Wednesday we have another match at the Camp Nou, against Celta, and it will start at 0-0. We have to follow this same path."
