From all indications, Bayern Munich are ready to forfeit every other trophy just to claim the title of Bundesliga this season again, which, to achieve that, they will have to be more consistent in their performance. That is why I don’t think Bayer Leverkusen will be able to meet up again, but still, it is a good achievement for them to win the title even if they will not be able to have anything in the Champions League; at least they will be able to be among the teams to participate next season, so to me, it is a good move for them. So let's see how their performance will be in the Champions League, although they are doing well in the domestic league, so it's still ok.
But no team wants to sacrifice another tournament to do well in one league. Bayern Munich have been performing well in the German league since the beginning of this season and if they continue that consistent performance so far, Bayern Munich might end up winning the league title. Now the talk is whether Bayern Munich are sacrificing another tournament to win their league title.
Since Bayern Munich has survived in the Champions League competition so far, it may seem to many that they may not give much importance to the Champions League but they will give more importance to the local league. But the point here is that to do well in the Champions League, they need to add strength to their squad, which they don't have at the moment. Maybe they will try their best to do well in the Champions League but in the end they might not go very far with this team.
I would say, if we were talking about domestic cup, giving that up is a good decision, makes no sense. But if they have a chance to win UCL, they would do that and risk bundesliga, since they have a ton of points advantage, they would be willing to lose a few games and still would be leading.
I do not think Bayern will win the UCL even if they wanted to, I think they do have a chance, but there are many other teams, so it's tough. It is not impossible, we could see them win it, there is a fighters chance for it, but they shouldn't put it all on the line for it. Just see how it goes versus Leverkusen first, those two games will be the most important games ever and wouldn't really be that much of a big deal at all if you ask me.
