Many people think Bayern Munich made a mistake when they hired Kompaney in this team because he is not experienced and he cannot be a good coach in Bayern Munich based on the last performance we saw from this coach but the fact about Bayern Munich and Kompaney is we still didn't see anything from this coach and there is the chance for him to have a good performance there in Bayern Munich. On the other hand, Bayern Munich had no other choice than Kompany because many other coaches rejected an offer from Bayern Munich.
We would never know if it's a mistake or not, the season will tell and it he's giving time, the season after that. What we do know is that it's an unusual decision. Bayern don't offen hire legend managers but at least they go for people that have done well in top level football. Kompany hasn't done that and only time will tell.
He has the right ideas, because he tried it with Burnley but we also do not know if he'll be able to execute it with better players at Bayern Munich.
I don't believe Bayern did not have any other choice. A couple of coaches rejected them, but that doesn't mean they didn't have a job. If they wanted they could have kept looking for a manger that would take the job if they didn't want to go with Kompany. A club like Bayern Munich won't hire a manger like Kompany just because they don't have a choice.
And also, those other managers rejected probably because of a clause in the contract.
