To date, Bayern has tried six candidates for the team's technical command, but has been rejected by all of them... Xabi Alonso (from Bayer Leverkusen), Julian Nagelsmann (from Germany), Ralf Rangnick (from Austria), Oliver Glasner ( from Crystal Palace) and Roger Schmidt (from Benfica).
So I'm not too surprised that they're going after someone "less coveted" like Kompany.
Maybe it's not a bad option, a change of scenery could be good for Bayern and also for Kompany who could do a very good job and silence the media's criticism. In any case, I don't believe that Bayer will sign a very long contract with the company... they should start with an evaluation period while keeping an eye on another technician who may be "surplus" on the market.
If they can't get a new coach, why they don't try to keep Tuchel as the coach. I think it is too early to fire him, Tuchel should have another chance to improve the performance of Bayern Munich. Anyway, I don't see those candidates better than Tuchel, except Xabi Alonso. We know Xabi Alonso has announced that he stays in Leverkusen, so there is no way that he will move to Bayern Munich.
Personally, I'm surprised, I don't think Bayern management have a lower quality of the candidate to replace Tuchel. Sure, Kompany can try to do his best with Bayern Munich. So he can show to the media that he also has a proper quality to manage Bayern Munich. But I'm very sure that it will be difficult for him to do the job. I doubt if he will get a big trust from the players because he still can't prove his quality as the manager. Unless it is the club where he ever played, I am very doubtful if Kompany can surprise us.
