I think it is not easy for Vincent Kompany to be able to give the UCL title this season even though their main competitors Real Madrid and Man City are having difficulties but there are Liverpool and Barcelona who are still performing well in the UCL and will be Bayern's competitors, I think it makes more sense for him to give the Bundesliga title to Bayern which was broken by Leverkusen last season, the situation in the Bundesliga is also not safe because Leverkusen is still trying to put pressure on Bayern at the top of the standings.
I also think that what you said makes more sense for Vincent Kompany this season, because he will still be considered good and extraordinary in coaching the Bayern Munich team if he is able to give the Bundesliga trophy to the Bayern Munich team this season even though he is unable to get the UCL trophy because this season Liverpool is very strong in all competitions. So Vincent Kompany only needs to try in the Bundesliga but it would also be quite good if he could enter the UCL final this season.
Vincent Kompany is really quite good but if we compare with other teams, of course it is quite difficult challenges this season even though there is no Real Madrid and Manchester City, but they will rise if they enter the play off to compete again, champions The Champions League for Bayern Munich is very difficult but it is not impossible for him to achieve, the opportunity is quite wide and he can still try hard.
The League Bundes is also imagined by Leverkusen, just look at them enough to be confident challenging Bayern Munich, not only in the League Bundes but in the Champions League too, I think we will see how far Vincent Kompany will pass with Bayern Munich this season.
