In my opinion, Bayern Munich made the biggest mistake by sending Nagelsmann. Of course, there will be some teams that want to evaluate this. It could be Tottenham, it could be Chelsea. The coming days will show us this. What I see is that he is a very good coach despite being a younger manager. Bayern will realize their mistake sooner or later.
They will only regret it Tuchel doesn’t do well. It was a rash decision by the board but we all know how salty their relationship have been since the Villarreal loss last year. They also think it is wise to bring in an experience coach that matches Pep in class and Tuchel was there only answer.
I don't think he should've been fired, he's an amazing coach. But one thing is that Bayern Munich is so used to winning the league with huge margins that they couldn't bear seeing themselves 2nd. Unfortunately this could lead to their own downfall. However, when you have the team that Bayern has, 7 league draws is unnacceptable, especially in the Bundesliga.
