Barcelona have really picked form of recent,and are pushing it hard to remain at the second position they are, although they know it won't be possible to meet up the points Real Madrid have already accumulated this season.They are in the quater finals of the champions league and would want to do everything possible to get to the semi final knowing fully well that the champions league trophy is the only thing they stand to achieve now,as Madrid are already on the verge of claiming the Lalliga Tittle after Barca won it from them last season.
You shouldn't be so confident, the point difference is only 8. If Real Madrid loses points in the upcoming matches against Athletic Bilbao or Mallorca, El Clasico may be more stressful. After 3 weeks, the score difference may be 2 instead of 8. Can you imagine the amount of pressure Real Madrid would feel in such a situation? There are still 9 weeks to play and a potential 27 points. I don't think Real Madrid can collect all these points. It's too early for them to celebrate. It should also be taken into account that Barca has been playing very well lately.
