Bayern Munich changing coach by this time is what we call try your luck, anything can happen and they shouldn't expect much from Tuchel in this critical time of the champions League. This is a wrong timing of bringing a coach to win the Champions league. I'm not too sure about Bayern for now.
Don't you even aware of the history of tuchel? Tuchel had ever been in the same situation when he replaced Frank Lampard and he successfully gave Chelsea three trophies. Bavarians can also expect the same thing to happen with them since tuchel was on their side. Tuchel is far superior compared with pep, which has been trying so many times to win UCL with city but it never happened. City was not barcelona prime.
Just because bayern was getting a new coach, and it doesn't mean if bayern will be losing easily against manchester city. The thing that you must remember is if anything can happen. you were feeling skeptical about tuchel but if tuchel will beat city and kicked it out from UCL and what's you going to say?
The thing that i do believe gonna happen in this match if bayern will able to beat manchester city even though city will be played with haaland on its side. Haaland never had a wonderful history against bayern.
He was always losing against bayern when he was still in the dortmund.
