I said it earlier in the thread the moment Messi returned is that I thought Barca played better (especially in the league) during the the time he was off and so far nothing have changed my mind.
Right now, they're playing with Messi +10 instead of playing as a team, when Messi was absent, Neymar, Alexis and Cesc were all showing their true qualities and more importantly helping there with the defensive transitions, Messi came back and all of a sudden, everything HAS to go through him like the others don't know how to play the ball, more importantly, Messi stands there in the final third and he rarely helps in any defensive work. That's one of the things I like about Suarez is that he's always on the defenders' toes.
I won't go as what Spanish Fan said or anything like that, but IMO, this season, he has been well below his standards. With Atletico's good season so far, I can see Barca finishing third this season to be honest.
