Although Freiburg is a dark horse team in the Bundesliga and they also started the season well after they managed to win over Stuttgart, visiting the Allianz Arena is not an easy task for them. Moreover, in the last meeting at the Allianz Arena, Freiburg suffered a crushing 3-0 defeat. So in my opinion, even though Freiburg this season comes with new strength and spirit and can be a threat to Bayern Munich, I am sure Bayern Munich will win this match. Moreover, in terms of squad, Bayern Munich is superior to Freiburg, so my prediction is that Bayern will win 3-1 in this match.
That's the main reason of Bayern Munich used a new coach and they got Tuchel fired from the team because they wanted to have better results in this season and now thanks to Kompany they have had good results so far.
Now, Bayern Munich has the chance to get back to the place it had been during the last few years.
