Real madrid is not longer the same team we know. It's really a shame to the great team playing like a small and disorganised team. I don't care whether they win or not but this is certainly one of the worst game I have witnessed them playing in a while. Imagine Real Madrid struggling against a team like Alves, what are we expecting when they face a much stronger team. With the way I noticed how they play with lack of spirit and desire to win, I don't think doing a comeback against Arsenal is achievable.
This sounds funny because they are technically still in all cup competitions and could win a treble if they turned things around 
Real Madrid is pretty much the same, there is not a lot of difference from the one of last season. That is how Ancelotti ball is. He lets the player's individual brilliance do much of the work and trust me, if Real Madrid turn up with a right mind set on Wednesday, they can throw out Arsenal.
All it needs is some spark from Rodrigo, Vini, Mbappé or Bellingham and the odds will change dramatically.
