He's the main culprit because he lost the ball way more than others and because he lost balls by trying his selfish moves and not through some team effort.
Oh, and because he is supposed to be our "main man" now but he is still closer to a circus boy.
Probably lost the ball a couple of times, but at least he had the BALLS to try something different in the build up to both goals, when our main striker decided to go "casper" on us, in such a sensitive game.
We won, he was instrumental in both goals, albeit having a shitty game, but I kind of have it difficult understanding how some people evaluate or rate a players performance WITH words like "he was the main culprit". Suarez did absolutely nothing other than run, Busquest gave a goal away, Raki was way too slow, Paco (not even going to say anything), Alba fluffed his lines in the first goal, yet someone who had a hand in both goals is tagged the main culprit. I have seen Messi have worse games than this, most noteable would be the one against RM (Varane). Its bound to happen to players once in a while, its a dip in form, but at least he is still very effective in team progress.
