Despite winning, I have a lot of criticisms of Bayern Munich's performance in this match, especially from the defensive side. Just imagine they conceded 2 goals from 2 chances created by the opponent, that for me is a bad thing. Even that happened when they were very dominant in the game. It seems that Kompany has to do a major evaluation of their players' performance after this match. Yes, they are the team that conceded the least goals, but their performance in this match was not satisfactory. They cannot let this happen, because if they are too comfortable then it will be very dangerous for them.
I too, often criticize Bayern Munich's performance under Vincent Kompany. It doesn't mean they play badly, but in several matches, especially against strong teams, both in the Bundesliga and in the Champions League. Regarding goals conceded, Bayern Munich is actually the team that conceded the least goals in the Bundesliga. The most important thing is how they still score a winning goal difference, even though they also conceded. Like in this match, for example, Daniel Peretz is not the main goalkeeper. Moreover, the first goal scored by Heidenheim was purely a mistake by Bayern's defenders. But apart from all that, in this match the Bayern players played quite impressively, although Leroy Sane, Alphonso Davies and the goalkeeper did not play so impressively. But overall they played well, Bayern dominated possession and had many opportunities. This kind of performance is expected from the matches played by Bayern Munich, especially when playing against strong teams or crucial matches. I hope that in the future Kompany will be able to improve the performance of his team, especially when they play big matches. Despite all that, Bayern Munich is still solid without defeat in 13 matches, they are advancing with a positive trend in the Bundesliga and are widening the points gap from their rival teams. If Kompany is able to maintain the consistency of his team, then the chance to win the League trophy again is even greater.
