There is a say that you will not appreciate what you have until you lose it, this is the problem that Bayern Munich is facing now as they shot themselves on the toe. It is so sad to see the team without a professional coach next season and that might not given Bayern a good result when the season ends because a lot needs to be put in place before Kompany will be able to win the title.
Kompany wants to sign players from England to join Bayern in order to see how he can improve the team performance and if he is able to sign good players, it is possible that he will be able to lead the club to win the title but I don't see that happening next season. Micheal Olise from Crytal Palace and Palhinha from Fulham.
It is a mystery why the Bayern Munich management appointed an inexperienced coach. But I would say Bayern Munich management is not stupid. They spend a lot of money to form squads. They have indeed appointed someone as inexperienced as Kompany as the coach of the team. However, Bayern Munich would definitely hire an experienced coach. This would increase Bayern Munich's chances of doing well in the Champions League.
Kompany was coach of Burnley. And this team could not qualify for the Premier League. Moreover, very few KOmpany have experienced the Champions League platform. So nothing can be said for sure whether Bayern Munich will be able to do well in the Champions League next season. However, it seems to me that the chances of Bayern Munich doing well in the Champions League next season are low.
