I also think the same as you that Bayern Munich is stronger in Bundesliga and more likely to win the domestic league title than winning the UCL title which is very difficult to achieve because the competition this season is very tight maybe Bayern Munich must face Liverpool if they want to win the UCL title because this club is at its best level both in UCL and EPL it seems Liverpool will be the strongest candidate to win the UCL this season than Bayern Munich.
The competition in the Champions League is always different from the domestic league so it will be quite realistic for Bayern Munich to target the Bundesliga trophy this season than the Champions League trophy this season. But if Bayern Munich can have the opportunity to go to the Champions League final, of course they will also try to win the trophy although for now I still have some doubts that Bayern Munich will be able to reach the Champions League final this season.
If we talk about the opportunities that exist, of course Munich currently has a pretty good chance in the domestic league, especially so far they are quite comfortable at the top of the standings by leaving Leverkusen in the second positions, but even so, I think it should not be for Kompany to only focus on the Bundesliga if indeed the depth of their current squad supports to also be able to stay focused and compete in the UCL, Kompany is not a coach who have experience in the UCL as a coach so far, but I think he has a heavy burden to be able to maximise their chances of remaining a title contender in the UCL, because it will be a great achievement for his career in first season coaching if he is able to present UCL and the Bundesliga trophies this season.
