I like the statement from the CEO of Bayern. Big clubs need to give the coach the opportunity over several seasons to be able to assess whether it is appropriate or not, suitable or not.
When a new coach is recruited to manage a team, the club monitors it and feels confident that the coach being monitored meets the desired criteria. This means that if you are to blame, the first person to blame is not the coach, but the club.

All these statements are worthless. Just remember what was said when Nagelsmann was hired and he had failures - “this is a long-term project, we are thinking 5 years ahead and blah blah blah.” Then he was abruptly fired mid-season

And although the initiators of the dismissal were later also forced to leave (Kan and Salihamidzic), this does not mean that Tuchel is safe. This season they gave him Kane - that is, everything he needs to solve all the issues with the existing squad, but it looks like he will lose the Bunedsliga title. Therefore, I think that if this happens, he will be fired in the summer.
