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.
