In my opinion, every management of a team has its own perspective when facing a problem. However, on average, the club will kick its coach when the team's performance falls. Bayern Munich management may have their own point of view or they have a long-term contract with Nagelsmann, so if the Munich management kicked him out, of course there will be a large compensation that must be paid. Besides, maybe it's still early in the season and management is still giving him time to improve Munich's performance.
So apparently Bayern Munich is not as good as expected this season? But it doesn't seem like a big problem because Bayern Munich's mentality is very strong to bounce back from some bad results in their last 4 matches. Bayern Munich is an established team, they are even very strong in Champions League but not good in their 4 domestic match.
If their current manager is fired, then I think management should prepare some money for compensation. That is stated in the coach's contract with the team, and every coach will get it if in the end the management wants to take a shortcut by expelling his coach.
