That injury list is like a joke. Real Madrid is really unlucky with injuries for a long time.

They had the same problem in the previous season as well. That's why Ancelotti should have signed an extra defender this summer.
He just said that he was satisfied with the number of options he had in the area. I wonder what he is thinking about this now. I assume Carvajal will be Rüdiger's mate there temporarily. I hope this temporary time won't be too long. Otherwise I think Real Madrid would have even bigger problems in the Champions League. Even against smaller teams I mean. Teams with good counter-attack skills can catch them off their guard.
The defense of every team is one of their strongest attributes in a match. If they’re lacking a good and strong defense, no matter how good they’re able to convert chances and score goals in the frontline, they will always concede goals and may cancel out the initial goals they’ve scored. Counter attack are a very strong vengeance on teams without good defense, they always fall back on their knees because the goals they scored cannot be protected by them till the end of the match because of the loophole in the defensive line. Real Madrid are a very competent team in the champions league, we may see their strength and what they’re capable of doing but when there is something of doubts, it may as well bring failure to them, so they should try and fix the problem in the defense also because of the effects it may have on them in the future in the champions league competitions.
