Bayern Munich should focus their attention on the UEFA Champions League because Bayern Leverkusen would not allow them to win the Bundesliga title this season. With the recent struggles of Bayern Munich, it will be hard for them to win the UEFA Champions League trophy this season.
Bayern won't let the league go. On the one hand, Stuttgart is only a few points behind and Bayern's minimum goal after the messed up season was to finish at least second in the league. On the other hand, the club has already indicated that the championship is not yet completely over. If Leverkusen weakens, Bayern wants to be there.
There is nothing Bayern Munich will do this season that will stop Bayern Leverkusen from winning the Bundesliga title this season. Bayern Leverkusen has played 27 matches this season without losing any, and I don't see them doing it now. Bayern Leverkusen is separately on a different level in the Bundesliga, and no club can stop them in the Bundesliga this season.
