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.
As I mentioned before, 1 goal advantage is not safe for Barca even though the match will take place at Barca's home, and it was also predicted that this would be a balanced match and the final result was difficult to predict, it's just that not being able to score a single goal in last night's match was very disappointing for Barca especially they are also not quite able to defend properly so they have to concede quite a lot of goals. Real Madrid always perform better when they are under pressure and Benzema brought his team to the final and by facing Osasuna in the final, it is clear that Real Madrid will be the favorites because Osasuna is always difficult to beat Real so this will be a trophy for Real after last year's championship 2014, and seeing Benzema score a hat-trick again is amazing because age doesn't diminish his sharpness.
