The Classical no only cost three points and the recent history of LaLiga​ has left this very clear. In fact, the data show that win the first Madrid-Barça of the campaign is used to to mark the League for well or for bad. The blow that supposes to fall against the eternal rival can retumbar in the time and the victorious this last decade has won the championship almost always. This is something to have very in account of face to the of this 18 December.

In the last ten years ten, the Barcelona has done with eight Leagues, whereas the Real Madrid only has won two. In this decade, the culés won in eight first Classical, whereas the merengues only did it in one of them. Win this first crash does not have why mean at all, although the last decade leaves clear that helps and a lot to encarrilar LaLiga.

It is necessary to take into account that the madridistas, usually, are used to to arrive to the Classical underneath of the Barça. This wants to say that fall in this crash has left in several occasions to the whites quite far of a Barcelona that is used to to be more regulate in the domestic championship. The psychological component has more importance of which seems and east is the best example.

In the last decade, the only times in which the Madrid arrived by in front of the Barça were in the campaigns 2009-10 and 2010-11. In both occasions, the Barcelona, that were a point underneath, attained to impose to go back to put by in front. In the course 10-11, besides, the result was the mythical 5-0 to the Madrid of Mourinho. The two Leagues would be for the barcelonistas to final of season.

Exits complicated the next weekend

Centring already in this course, before the Classical both groups have both proofs of level in fields complicated of LaLiga. The merengues visit to Valencia in Mestalla, whereas the culés follow suit with the Real Sociedad in the Reale Sand. If one of the two punctures, will have a lot of more pressure of face to the commitment of the 18 that the another.

A tie or a defeat of the Madrid in Valencia would mean that the Barcelona could leave him to five or six points in the Classical with a triumph. The ones of Zinedine Zidane already showed these last years that do not are used to to recover when they lose comba with the culés, by what can not allow go out to more than three points. The same could suceder, but to the reverse, if the one who punctured the next weekend went the team blaugrana. By all this, whatever happens in the Classical, both groups will have to give it all days before against the valencianistas and the 'txuri-urdin'.
