What I see today Munich has a few weaknesses in the defense and if Kompany wants to get a title this season, he must fix the problem. Because I'm sure Leverkusen will get a greater increase in the January transfer window.
And regarding the competition with Leverkusen, of course it is very natural and fierce, but now Bayern is still favored with the existing advantages.
I think the current problem is in the Champion League competition, the Bayern Munich team that performed well in the Bundesliga could not do the same in the UCL, that might be pressure for Kompany.
Kompany is a young coach and he is not as experienced as Xabi Alonso, especially in the Bundesliga. I think now Kompany should be careful because if he loses points in Bayern Munich, Kompany is ready to take their place in the table because right now there is just a little gap between these two teams which can give Xabi Alonsoa a good chance to get closer and even Leverkusen can take the first position of the table again like the last season and win the title.
However Leverkusen should hope to see Kompany make mistakes and Bayern Munich lose some points and let them get closer, while in the first games during this season, Kompany had a perfect performance and with the performance we saw from this coach, he can have the chance to win the Bundesliga title in the first year of working in Bayern Munich.
