Barcelona star Andres Iniesta has vowed that he and his team-mates will learn from their 5-4 victory over Deportivo La Coruna in La Liga on Saturday.
The visitors raced into a 3-0 lead before being pegged back to 3-2, but they held on to take all three points in a goal-laden encounter at Riazor.
The 28-year-old admitted that Tito Vilanova's men left with the feeling that it was a tough game, despite the easy start.
"[It was a] crazy match. We thought we had killed in the first half but Depor at the Riazor with its fans is difficult," Iniesta told reporters after the game.
"We leave with the feeling that we have played a tough game and this will make us learn."
On the issue of Javier Mascherano's red card and the penalty, the attacker was careful in his response ao as to not attract any controversy.
Iniesta continued: "The referee's job is always difficult. The penalty and the red card happened fast."
