Bayern Munich is a club that some big clubs wish not to meet in the knockout phase of the UEFA Champions League competition, but after some Bayern Munich key players retired, Bayern Munich lost their dominance in the UEFA Champions League, and they also struggled to maintain their dominance in the Bundesliga. But since Vincent Kompany managed to restore Bayern Munich's dominance in the Bundesliga and win the Bundesliga title this season, I believe Vincent Kompany will focus on also bringing back Bayern Munich's dominance in the UEFA Champions League next season.
I would not say "dominance", it's just they are unrivalled, no team in Bundesliga has the money Bayern has, so there is no way that Bayern could lose the title. In all of the leagues all around the world, if a team spends five times more than the other teams, then they are going to win the title. But UCL isn't like that.
Because there are other rich teams there, so Bayern is still not as good as their old self, back in the day they were one of the best in Europe too, not just Germany, now they are not there. I would guess they would not be a team to fear if we saw them do fine, like if any team faced them, it wouldn't be as scary as 5+ years ago, maybe back in the day it was a scary thing to face them, but not anymore because they are much worse.
