Kompany is not qualified to be the coach of Bayern Munich in my opinion.
Bayern's primary goal has always been the Champions League. Bayern is already champion in every way in the Bundesliga. Look at the last 20 years. The teams that have been champions other than Bayern are Dortmund and Leverkusen. These two teams came to my mind first. Their championship total is already known.
That's why Bayern always sets the Champions League as their primary goal but they can't reach this goal with Kompany. Also, Bayern Munich doesn't have any quality forwards other than Kane right now. Musiala was injured yesterday. They need to get a very quality forward urgently.
They will finish the league as champions again but the squad is not enough for the Champions League.
You made good points about Vincent Kompany as Bayern coach especially with their goal of winning Champions League. Bayern always aims for that trophy because they usually win German league easily. It is fair to question if Kompany with his limited top level coaching experience can lead them to Champions League title especially since it is big step up from managing Burnley. You are also right that Bayern attack relies too much on Harry Kane and they need more strong players up front especially with injuries like Musiala if they want to win in Europe. Kompany success will depend on his tactics and bringing in new players and how team plays for him making it exciting season for Bayern fans to watch.
