For Bayern Munich to win Dortmund it is a big win for Tuchel, atleast his first game as coach of Bayern Munich came out with a good result. The victory of the game will give fans good impression of Tuchel winning more games in Bundesliga and in Champions league. Interesting for Bayern Munich to maintain the top position.
this is a very good start for him and a good one for the team as a whole, it seems so far that they made a good change, it was unexpected but looks good so far after a win against a tough team like Dortmund and get ahead in the league.
