Just after the game finished many Real Madrid fans started attacking Barcelona because of their playing style they said Barcelona was defending during the game all the time and they didn't deserve victory at all because Real Madrid was controlling the game more than Barcelona and unlike other El Clasico we usually saw real Madrid had more successful passes comparing to Barcelona while the most important thing is the result this game is which Barcelona could bear Real Madrid even without players like Lewandowski and Perdi.
It is quite strange t know the fact because this is football where the coach must consider what will happen and what is best for their team at that time. And Barcelona has done their best tactic by playing more defense because they are aware that at that time they have weaker attacking lines because of the absences of several key players. And they deserve the victory because of Real Madrid's mistake. I don't know why Real Madrid only played the ball possession but they are not playing high attack from the beginning. This is such a very disappointing result of the El Classico match
