Yes, Real Madrid are going through a lot of ups and downs at the moment, due to which they lost their first match where they did not score a goal. The team is still very uncertain because of that, but they have many records in their past to come back. If Real Madrid can come back in their match against Arsenal today, it will be a huge comeback that all Madrid fans are waiting to see. If Real Madrid can come back from this situation, then only they can enter the semi-finals, and if their luck is not on their side, then there is a possibility of losing.
Come on, we can't underestimate Real Madrid, even if they are in a difficult moment. They have the potential to get back in the game, in every moment
The mistake that a competing team, say i don't know Barcelona, can make is to think they are safe. You always have to keep them far away in terms of points and how do you do that if not by winning?
