I really have no idea how Real Madrid won this El Clasico by 4-0 away. It was a Copa del Rey game maybe but both teams were caring about the cup anyway.
Barcelona actually started better but after some time Real Madrid started to play really amazingly. But I still can't believe Barcelona about how easy they lost their concentration this much. They even had a 1-0 score advantage before the beginning of this game. They were just demolished in their home stadium. Real Madrid should be able to go for the cup as well from now on. They really want this obviously.
The Real Madrid team and especially Karim Benzema who scored three goals against Barcelona put on an amazing performance. Due to the fact that the most important rival of Real Madrid has been kicked out of the Copa del Rey, Real Madrid now has a greater chance of winning the trophy, and on the other hand, after losing three El Clasico games in the season, the team may be able to finally retaliate against Barcelona.
