It had everything to do with ignorance. ignoring managers instructions . If it was Busi or Messi i would have blamed them as well .
Nope you dont have a clue and it is not as simple as that.
He made a mistake as did many others if you want to boil down those fouls to being ignorant of managers instructions.
Busi did foul. The only reason is Barca defended that set piece as had done with every other one during the game.
Messi or Neymar contribute to the result by missing chances to go 2-0 up. Whoever was marking Ramos and disappears contributes.
All played a part in Barca not winning that game.
