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.
Bayern took a risk to appoint a new coach before such an important match in Bundesliga but that seems to worth it with such beautiful victory against their main opponent Dortmund. 4 - 2 was kinda good result. Dortmund attacked and were somehow successful at the end of the game by scoring 2 goals but weren't able to get a draw.
Bayern got back the first place with 2 points difference from Dortmund. Freiburg, Leipzig and Frankfurt kept the same position with their negative results.
