The Catalans defend a 2-0 lead from the first leg when they host their arch rivals next week, but the Argentina international has warned that it's not over yet
Nevertheless, highly-rated midfielder Javier Mascherano has warned his teammates that the tie isn't over just yet as Madrid will do their utmost to fight back in Barcelona next week.
"I'm very content with the outcome from this match, but this doesn't change anything about the second leg. There is another game to be played and Real Madrid are a very strong team that will do their utmost to turn things around," said Mascherano to AS.
"It will be a very difficult encounter at Camp Nou. Real Madrid are a great rival and won't give up after this match."
Mascherano refused to comment on the referee's decision to dismiss Real Madrid's Pepe after the break.
"I have nothing to say on the incident as I didn't see it very well. The important thing for me is that we were true to our philosophy. That makes me a happy and satisfied person," he concluded.
