The ref was a disgrace in the 2nd half. After Chiello scored, the referee turned into parental mode for barcelona and tried to get them out of their misery in every play.
We got cards out of nowhere and a lot of bad calls and a goal nullified. The only good thing he did was to not call the Chiello PK because he thought it was not intentional.... but apart from that the guy was heavily favouring a catastrophic barcelona.
