It is possible that Bayern Munchen management no longer has many choices, so they appointed Kompany as manager next season. Another consideration is pursuing time to prepare the team, when the transfer window opens, the position of Bayern Munchen manager will no longer be empty. To be fair and not to underestimate Kompany, despite many doubts about him, he deserves time to show his tactical qualities. With the vast difference in squad depth between Bayern Munchen and Burnley, it seems Kompany efforts will be easier.
Bayern Munich staff made a huge communication mistake by announcing that Tuchel will be fired and before that they fired Nagelsmann and since they made these acts, other top coaches refused to take the team on charge. They asked Nagelsmann to return and he refused and for obvious reasons, Tuchel decided to not listen for them to continue training the team after they fired him. Leopard ate my face like they said, Bayern Munich fantastic staff decided to hire Kompany that I assume will not last long than the first six games if he fails to maintain Bayern Munich in the top position.
