I would definitely blame Bayan Munich's defense position for the draw because if they could have performed a bit better, Bayan Munich might have had three points in this match. Points cannot be lost like this, if they don't perform as planned in the upcoming matches, they may regret it at the end of the season.
That is the problem with Bayern Munich right now, their defense is starting to become fragile, unlike at the beginning of the season. The draw against Frankfurt proved that Kompany really needs to improve his team's defense. Things will be difficult in the future. They could regret it at the end of the season, the competition in the Bundesliga is getting tighter with the arrival of new competitors. We see the standings of Frankfurt, Freiburg, Leipzig, Union Berlin showing the competition, if they remain consistent, it is not impossible that at the end of the season there will be a surprise.
We saw Bayern Munich sell a key defender to Manchester United earlier in the season, and seeing them sell a defender seems like they may be overconfident in their defensive positions. But what happened to their confidence, with the confidence they sold an important defender to Manchester United, now they have to worry about the defense position the most. Bayern Munich are able to score goals against a relatively weak team with good midfield and attacking positions. By a good team we mean that there will be no weakness anywhere in the team but currently Bayern Munich has a clear weakness in the defense position. Until Bayern Munich work on this weakness and they can recruit a good one, their dream of winning a major tournament title will remain a dream.
