I agree with you that many fans have really underestimated this Bayern Munich this season just because they are managed by Kompany who man think his limited knowledge and experience will hinder the club’s progress, many still want him out as they believe he is not the right choice, but my emphasis has always been that he fits perfectly for the club to me due to how his style. At his former clubs he couldn’t implement his pattern of play because of the players there but at Bayern Munich he has the quality of players to play that styles.
I wasn’t surprised with the win today because i had predicted that Bayern Munich will definitely try to take advantage of the the points dropped by their rivals or title contenders, so it was a much needed and also well deserved win.

As for Stuttgart, I had predicted them running into difficulties this season due to their sales of players and them not being able to replace most of them. Now they will add the Champions league football to their games which is definitely going to affect them if they remain in this current form.
Heidenheim on the other hand since last season have shown similar characteristics like when Leipzig was promoted first to the champions league, last season many expected their drop back to the lower division but they stayed and even went ahead to get a spot at this season’s European competitions. They picked up right where they left off and I think they will grow more and would be a huge threat to just any club this season
