I'm the last one to defend Madrid, but poor refereeing in someone's favor is also robbery.... along with the legitimate goal canceled, the match should have also ended at the time Barca was starting the build up for the final goal, and also Messi's second goal could easily be called as a offensive foul, as it was ! So, let's say Messi's goal for M'bia's yellow.... and what about our goal and the extra-extra-time ?
Refereeing in La Liga needs some serious investigation. If things go like this, no wonder why La Liga is not mentioned as the best league. I don't even want to spend time to convince some (friends) die-hard Premier League or Serie A fan to watch La Liga matches besides El Clasico.
It is a pity and a shame to football. This must stop now ! Teams giving their best for 90 minutes and then robbed by some silly referee... they should be imprisoned to mess with player's sweat on the pitch, risking even their health and career to battle and do the best for their team.
