The big win that Real Madrid got seemed to send a signal to Barcelona, that they were in combat-ready condition to play at Camp Nou in the second leg. This win is also a big motivation for Real Madrid to face Barcelona and I think this will be quite a challenging El Clasico.
In this game, Benzemas hattrick was sensational. Only 7 minutes for 3 goals and now he has a good chance to be the best scorer in the league. Lewandowski has only 3 goals more and there are still 11 games to play. Too bad he was substituted in the 65th minute, maybe he scored another goal. FC Barcelona will not be impressed, they are extremely motivated and have their eyes on the Championship. I think it is already 80% done that Barcelona will win this year.
