Right now, I think Bayern Munich is focused on the Bundesliga instead of the Champions League. Because Bayer Leverkusen achieved great success in the Bundesliga.-snip-
Apart from the fact that Bayern Munich failed to win the Bundesliga in the previous season, they are also playing with a new coach this season. Vincent Kompany is a good coach but I think we can't talk about the UCL yet because new coaches usually need time to adapt. I think the first realistic target is to win the Bundesliga. I think the club management wants Kompany to focus on the Bundesliga first. The UCL is a different level and I think if Kompany can give good results for the club, it will still take time to build a solid squad.
There has been no proof of Vincent Kompany's coaching so I don't think he is worthy of being called a good coach.
Bayern certainly prioritizes the Bundesliga to be able to win it again after their dominance was broken by Leverkusen last season and for a team as big as Bayern, of course, they don't ignore the Champions League either.
We can't give any assessment for Vincent Kompany, in the first Bundesliga match Bayern did win but I don't think that's enough to say that Vincent Kompany has given a positive effect or made Bayern much better this season.
