"Not scoring? I'm not worried about scoring, that's not the goal of a game," said Messi. "The goal is to win the game."
Messi then turned his attention to Barca's clash with Real Madrid in La Liga on Sunday.

Barcelona currently lead the league table with 18 points from six matches, eight points clear of Madrid, who are sixth.
