Real Madrid are still favorites in the Champions League even though their performance this season is not very good. I know Real Madrid is a good team to hope to come back and improve their performance, so things will change so quickly for them. Real Madrid has lost 6 points from 4 matches, while they still have 4 matches that they can all win. The match against Liverpool is certainly very tough, but that doesn't mean Real Madrid will fail to win it.
If in the end Real Madrid loses this match, it will be their third defeat this season in the Champions League. Everything was getting heavier and more chaotic, but I didn't expect the defeat to become a reality.
It is hard to expect Real Madrid to be at their best every season, last season was a success for them and this time they have problems with injuries and it has mostly affected their defense. After they lost Carvajal it was clear that this would be a big problem for Real, after another injury to Courtois it got even worse and after an injury to Militao that kept him out for the rest of the season it got even worse. It is obvious that now the weakest line for Real is the defense and this may not allow them to achieve anything significant this season.
