I don't think Real Madrid is in a good situation right now, they nearly lost the La Liga title to Barcelona and there is o hope for them anymore and this can have a negative effect on the team, however, they have enough time to recover. On the other hand, Bayern Munich started working with a new coach and we can't be sure how they are going to perform even in Bundesliga also he needs some time with his team. While Napoli got a more stable situation.
Now with conditions like this actually for Madrid they just have to focus on the Champions League so they can bring back this trophy because indeed with the current domestic league which is bad it is clear that this is very unprofitable for them and we all also know for sure that their position in La Liga unprofitable because it lags far enough. Even though there is no word of surrender in the league, their focus must be bigger on the Champions Legaue for now.
