Muller names one thing that separates Barca from the world-class teams

"Technically and tactically, they are all great players. But they cannot keep up with the intensity that is currently prevalent in top-class football. We have also made use of that," Thomas Muller said after the Barcelona game.

The Catalans have lost twice to Bayern Munich this season, conceding six goals and scoring zero. Barca have finished in the third spot in their group and have been relegated to the Europa League.

This Champions League season, Blaugrana have recorded two wins, a draw and three losses.
