This match is actually a very controversial one and even getting one point, Barcelona already fell behind Real Madrid in La Liga ranking table. This disappointed draw even with a good start, is a big alarm for Barcelona, that they must play more carefully in coming matches as well as in this season. Real Madrid in this season are different than the last one and they will be better able to take advantage of Barcelona mistakes as well as dropped points.
Barcelona could not win this match. But there is no denying that Rayo vallecano played great. I was just surprised by their performance. Despite Barcelona being a strong team, Vallecano players were able to play very well. And due to such a great performance of Vallecano, Barcelona was under a lot of pressure. And in the end , Barcelona had to be happy with 1 point. If lewandowski had been in the starting XI, maybe Barcelona would not have missed easy chances and would have been able to score a few more goals. There are several weaknesses in Barcelona's overall performance that are visible. They need to play better if they want to dominate La Liga.
