With regards to what is happening to Real Madrid in the La Liga now we shouldn't be too confident about them winning the Champions League this season because literally, no one expected them to face this difficulty they found themselves in the La Liga now and considering the level of injuries that has hit the club is already sending a message that things may not really work so well for the team as everyone thought it will. However, Real Madrid is an elite club with quality players so regardless of the injury concerns they can still perform better and possibly claim the UCL again.
We have to see how deep the squad is that Madrid has. even though some players are injured, it will not affect Madrid. because they have many player options that I think are not much different in quality. unless Vinicius, Mbappe, and Rodrygo are injured at the same time. that might be serious for Ancelotti. if the situation happens in another team, it might be very influential. but for Madrid, I'm sure they can still perform well. but we also see whether the new system used for the group stage with 8 matches will benefit Madrid or not.
