He plays like shit, because he is put out of his natural position. Much like Rakitic. They both play very deep and close to sidelines. As if we had 3 Biscuits in a line. That is because our forwards don't track back to press enough and our fullbacks bomb forward too much, making both of our central mids being burdened with too much defensive work and pulled in backwards positions. Very stupid imo because at least Alves contributes nothing to offense and is utter stinker as a defender, while Alba, although more useful, could still play more conservatively to allow Iniesta do his magic upfront more. Given that today it was Adriano, who has gotten fat and slow, it was even more defensive work for him.
Given that Rafinha was nowhere to be seen, and despite what delusions some people have, Alves is utter dung offensively, both of our flanks were utterly impotent. Nor Neymar or Messi had anyone to play ball with, which is why there were so many attempts at individual dribbles and opportunistic passes towards Suarez.
