What I’m getting from everything at Bayern is that there’s something seriously wrong behind the scenes as Alonso, Rangnick and Nagelsmaan have all definitely turned down the job whilst Tuchel has said publicly he’s leaving and it looks like De Zerbi is staying at Brighton.
I won’t pretend I know the ins and outs of Bayern but there must be some kind of behind the scenes power struggle or battle going on as Nagelsmaan and Tuchel have been fired then attempts made to bring them back/keep them, didn’t they change the boardroom in the summer ?
If you list de Zerbi, you also have to mention at least Emery and Hoeneß who also were rumoured to be candidates but extended their current contracts. And yes, there has been a lot of power struggles in recent times. In former years Rummenigge and Hoeneß were leading the club. The "new generation" setup looked the following (only most important/relevant people):
Herbert Hainer - club president and head of the supervisory board of the corporation "FC Bayern München AG" which is running the football business and the key entity here - but keep in mind that it's a separate entity to the actual club.
Uli Hoeneß - member of the supervisory board
Karl-Heinz Rummenigge - member of the supervisory board
Oliver Kahn - CEO
Hasan Salihamidzic - Chief Sports Officer
Christian Dreesen - Chief Finances Officer (had that position for ages)
Marco Neppe - Technical Director
Christoph Freund - Sports Director (last of those to arrive)
Salihamidzic got his job already while Rummenigge was still CEO. Kahn and Salihamidzic worked to get Nagelsmann and were investing massive money in him, it was also these two who got rid of him and replaced him with Tuchel, which was seen as massively burning money and a huge gamble. When it became clear it hadn't paid off the supervisory board decided to fire those two just before the final matchday of last season, they even prohibited Kahn from joining the team and the celebrations when they surprisingly won the title then. Apparently he personally took it very bad, Salihamidzic was present so probably reacted in a different way
They then promoted Dreesen to become the new CEO and had to work with a makeshift structure during the summer. And it didn't work that well, which saw Marco Neppe fired as well - he apparently didn't perform as well during contract negotiations as hoped and the "old guard" had to step in to get things done. Still they fecked up several transfers (like Palinha on deadline day) and left Tuchel with a thin squad, much thinner they had planned. While Tuchel complained about that Dreesen brushed that aside with "he has to find solutions, that's what we pay him for". So there relationship was quite strained I think.
Therefore Bayern were running for most of the season without an executive level sports official and when it became clear that the season doesn't work very well Dreesen decided to fire Tuchel, probably with backing from Hoeneß. Very shortly after that they signed Max Eberl to become their new CSO. Who walked into a club that just fired a manager he wouldn't have fired and tasked him with finding a replacement (sidenote: the exact opposite of what's happening at United where nobody moves until the new sporting structure is in place).
So Bayern at the moment have an "old guard" that stepped in and keeps involved much more than they should and a "new guard" who have to prove that they actually are allowed to make decisions and can stand by them. Problem is, as Kahn/Salihamidzic proved even as a CEO you are quickly replacable if the former executives don't like your work.
So nobody knows who really makes decisions and the club and who really needs to back you when you become their new manager.
