Bayern Munich’s performances in the Bundesliga have indeed been much better and they have managed to become strong contenders for the title this season although that position is not necessarily safe because Leverkusen are still looming over them in second place. But if we talk about the Champions League I have doubts about them because there has been no improvement this season in competing so their chances are very small. Harry Kane is not the only player who has scored goals for Bayern Munich and even though he is out with an injury there are other players who are capable of scoring goals. Harry Kane's productivity in scoring goals is indeed much better and that is because of his position as a pure striker so it is natural that he is one of the top scorers for Bayern Munich.
Regardless of Bayern Munich's condition this season which has improved quite a bit, but if in the second half of this season Leverkusen can make a more solid difference in terms of its own performance, of course Leverkusen still has a chance to catch up with Munich at the top of the standings. Likewise with other competitions such as the Champions League where Leverkusen could qualify for the next round without having to go through the playoffs, while Munich still has to fight to win with a higher score in order to place itself in the top eight zone in the Champions League to be able to get through this.
You can say bayan munich is doing slightly better in german league this season but if you talk about champions league then i would say bayern munich is doing worse this season in champions league than last season. Leverkusen finished the whole season last season if they could continue this season with the performance of last season then we could see Bayern Munich not being very effective in the German league. One thing you might notice is that Leverkusen had a considerable points gap with Bayern Munich but now that gap is slowly closing. If Bayern Munich doesn't perform as expected in a few matches, it could be that Leverkusen overtakes Bayern Munich to occupy the top spot in the points table. So Bayern Munich should be careful in advance.
