When Thomas Tuchel came to replace him, there were many unknowns about Kompany. Many people criticized the management because of this manager. Everyone said that Bayern Munich should work with a very good and famous manager with a successful career. However, Kompany has misled many people and is playing above expectations in both the Bundesliga and the Champions League. Kompany was able to achieve this and I think he did not disappoint the trust in him.
In the Champions League, Bayern Munich has so far been able to be in the top ten and there is indeed a possibility of being in the top eight zone after playing two more matches in the standings. But I am more convinced that Bayern Munich will be stronger in the Bundesliga than in the Champions League because the pressure that Kompany must accept in the Champions League is still much greater than in the Bundesliga. So I am a little less sure that Munich can go far in the Champions League, but if it is just in the Bundesliga, I am still quite sure that Munich can maintain its top position until the end of the season.
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.
It's hard to say, because you can only judge from the domestic championship, to understand their level, you need to meet them in the Champions League, otherwise there is no point in comparing, you can only make a dry guess. In fact, Bayern look very good now, even in the domestic league, but in the Champions League they still have a lot of work to do
