Lionel Messi played down his personal achievement after scoring four goals against Arsenal FC to take FC Barcelona into the UEFA Champions League semi-finals, saying: "What I did isn't so important but the performance of the team as a whole is what counted. It wasn't a good start for us but thankfully everything worked out well in the end and I'm just really happy that we won the game. The semi-finals will be a difficult tie and we must continue working hard if we want to reach the final."
