If we talk about the titles that Bayern Munich can win this season. in the DFB pokal Bayern Munich has been eliminated. of course it will not be able to get the title from the DFB pokal. in the Bundesliga, the points are very far behind leverkusen so it is also impossible to get the title from the Bundesliga. the remaining titles this season that Bayern Munich can win are only in the champion league, it will be very heavy.
Yes, Bayern Munich has lost the opportunity to win the title you mentioned and the only hope for Munich this season is to win the UCL title and that is quite a difficult title because the level of competition is more difficult than the domestic league. At least Munich has to get rid of Real Madrid. Man City and Inter are first if they want to get the title but it doesn't seem like an easy task because these teams are still performing well to date and to be able to win the UCL title is a miracle for Munich but at least they didn't just give up even though they failed to defend the domestic league title this season.
Leverkusen clearly cannot be stopped, from the start of the season until now without losing is a result that Bayern Munich cannot achieve, so by any means necessary to force them to catch up, I believe it is impossible. 9 matches remain and if Leverkusen manages to get through all of them without defeat then a trophy award will still be lacking for their performance during this 1 season.
There is 1 trophy left that Bayern Munich can compete for but it is also not easy, UCL has stronger candidates. The teams that qualify for the top 8 are the teams with the most consistency which is quite good in their respective leagues. The draw for the round of 8 will really determine the fate of Bayern Munich. If faced with any club it will still be difficult, especially if it is Man City, Inter or Real Madrid then we cannot completely guarantee that Bayern will easily get to the final.
