Apart from Valdes no player really shined that much, the whole team looked tired, especially Xavi (who still had a decent game).
Valdes - saved the day against a very good Valencia
Alves - pretty solid in defense (don't blame him for the goal as he did the right thing) and should've had an assist for Villa
Messi - a bit anonymous but did make some decent passes, also one great one to Cesc, as well as smashing in a perfect penalty
Honorable mentions: Alba (good defending), Busquets (first half), Xavi, Pedro (winning the pen, albeit it was mostly Pereiras stupidity)
