The chances for Barcelona to catch up with Real Madrid points is very slim, and I must tell you that in the El Classico match to be played this evening, that Real Madrid will win Barcelona and increasing the points difference, which makes it to be impossible for catching them up to happen.
Barcelona might have come back to their normal dorm but, it will be a very difficult task for them to win Real Madrid even though, they are the defending champions. Real Madrid is also in their best form and Ancelotti will make sure that he comes up with a better strategy that will overpower Xavi's own tactics.
This will not be easy even though Real Madrid will be playing at home, as has happened in the past, El Classico matches are always fierce and Barcelona's current performance is much more developed so they cannot be underestimated.
It's not just a motivation to chase points in the standings, but the El Classico match is a prestigious match for both teams so I don't think that the difference in points in the standings alone is used as a reference and also overall Barcelona's performance I think can match Real Madrid so I predict Barcelona will not lose in the El Classico match tonight.
