I really don't understand you or am I mistaken it for something because know that Real Madrid are currently the champion, and also they are known as champion of all time, Real Madrid is among the top teams that know how to play when it comes to champions league, must of the Cup they took, they didn't started with an aggression of winning the trophy, slowly but surely they arrived at the required destinations and that is what everyone are aiming for. Seeing them in 20th place in the table doesn't me they are out but if they have good record and stay in the top ten is better. So far they are not in the 25-36 they have a bigger hope of winning the title. Even PSG that are still in 25th place have hope of winning the title, because they still have more games to play.
It's understandable to not have them as your number one candidate to win this season considering they are 20th, not saying that they will lose or anything like that, Real Madrid could still end up winning this season there is no doubt about that but I could still see how people may doubt that considering the results they have gotten so far. If they keep playing like they have played so far then we could assume that they may end up losing in the end, it would make sense they would regain momentum and win though, so we just need to wait and see how they will do.
To be fair, there are other good teams at UCL this season, so even if Real Madrid does end up winning again, which I doubt it will happen, then they would have to beat many great teams this season and that makes things harder for them.
