Bayern Munich suffered a surprise defeat. No one should be blamed for this because they are the only ones to blame. They played ineffectively throughout the match. They actually played well but the Mainz defense was very good, they couldn't get past them. Of course the Bundesliga is a 34-match marathon. Of course there can be such defeats, the important thing is that they are not too many. They are not very good in the Champions League this year either. The players need to learn from their mistakes and look at the matches ahead.
Bayern Munich's defeat proved that Kompanty is very dependent on striker Harry Kane. When Kane was absent, Bayern Munich had difficulty breaking down the opponent's defense, in this case Mainz's defense, to score goals. This can also be seen from the actual game statistics. Bayern Munich dominated the match with 69% ball possession and released 13 shots, but they only managed to make 1 shot on target and it was ineffective. Without Harry Kane, Bayern Munich could not win the match and this was their first defeat after 13 matches without defeat.
On the other hand, in this match Mainz also appeared very effective and clinical. It was seen that they tried 8 attempts at kicks and 4 of them were on target, even though they only got 31% ball possession but they played very effectively. In the end, Mainz gave Bayern Munich their first defeat in the Bundesliga, this defeat not only made Kompanty have to learn from his mistakes but he also had to be able to play the role of all players without having to rely on just one player. So if there is an injured player he can utilize the potential of other players.
