I think it is too early to say that Real Madrid will lose the Champions League, because they still have a chance anyway and if they improve in a short time it will make them a big contender for the title again.
We are in the league stage and Real Madrid still have a chance in the league stage, yes although most likely they will be in the play offs and have to win to qualify for the knock outs.
No, it's not that he's going to lose it, it's just that he's walking on a tightrope, but they've already been recovering, so now the question is the UCL, they have to win or win, they can't even draw or anything, they have to ensure it would be very sad if Madrid were no longer there for this UCL, until now Mbappé has recovered and I like what he's doing, it's a nice gesture that he has finally regained a little confidence after that goal against Girona, really after he did it he was another Mbappé, now I hope he maintains that level, people have criticized him a lot, they have even compared him to Hazard, but no, he's still very new in the team.
