In La Liga it really already seems that there is no chance, despite the fact that there are still a sufficient number of matches, but if we assume that Barcelona should lose these matches (albeit not all), which is impossible in principle. On the other hand Real Madrid still have a chance to take the Champions League trophy, and the chance is great enough
It will be difficult for Barcelona to lose their remaining games. Barcelona have won won good numbers of game that even if they don't win all of their remaining match real madrid can't still meet them. Real Madrid knows where they have hope of winning a trophy is the Champions League.
