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.
Their chances in the champions league are indeed difficult, especially if we judge their sometimes disappointing performances, especially Bayern Munich's competitors in the champions league this season can perform better in their respective local competitions so it is quite understandable if they are in doubt, but Bayern Munich in the champions league cannot completely underestimated because they are a team that has won several times there so the opportunity is still there, they just need to focus on the matches in the champions league because the Bundesliga title is impossible to get seeing how Bayer Leverkusen tries to minimize mistakes, Bayer Leverkusen seems to be trying to appear perfect without any matches being played just underestimated even though the opponent is a weak team, so in just a few weeks we will see Bayer Leverkusen become Bundesliga champions
