I am really confused whether the match was between Barcelona and Real Madrid or Barcelona and the referee. After watching today's match I am confused about the definition of handball. From my point of view the referee's decision was definitely controversial and in favor of Real Madrid. Such a decision at crucial moments of the match could have resulted in a loss for Barcelona. Although Barcelona won the match in the end. The two handballs and the offside decision were very controversial. Even the commentators were confused about the referee's decisions.
You should not be surprised about the referee because controversy or not from the point of view of the fans of one team it sometimes looks disadvantageous or maybe vice versa. But in the end the result is determined Barcelona was able to give a heavy blow to Real Madrid this season. all El Clasico meetings have been won by Barcelona, the La Liga title is certainly locked in by them.
