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
If you are a Real Madrid supporter, then try to forget about La Liga this season and start focusing on the Champions League or the Copa Del Rey. La Liga is a dead horse for Real Madrid after Barcelona is 12 points ahead, even though the towel is still in hand but you better forget about La Liga. It's hard to expect Barcelona to get 4 defeats while Real Madrid must win all the matches, it's impossible even though Real Madrid is a big team.
