It seems unfair to Nagelsmann, and the same thing is felt by Thomas Tuchel, because Tuchel must also be able to realize expectations in a short time of preparation, yes he must quickly understand this club as a whole so he can implement the best of his strategy. This has already happened, we can only see if this is the right decision made by Bayern Munich or vice versa. Obviously it won't be easy, but we'll see them in the next few days.
Basically apart from anything, conditions like this must be something common for big clubs that really want something more. Even though Nagelsmann's performance is still very good, the fact is not a guarantee when Bayern officials want something more like that with Tuchel, although for the case of Tuchel it seems he doesn't really like and hold on to Todd so that he is in the depak quickly. But indeed that is common because being in a big club is definitely the president will also be big and when it is not agreed, dismissal is something that is certain.
