I don't see much chance for Leverkusen to win the title this season. This team did great last season and they went undefeated to win the local league title but this season is definitely tough for them. Bayern Munich have played two matches so far this season where they have earned full points in both matches. Leverkusen, on the other hand, have played two matches but lost one, meaning they are currently 3 points behind Bayern Munich. If we compare the performance of Leverkusen with Dortmund then we must put Bayern Munich ahead in the performance of the first two matches because they have not lost any of the two matches, they have won one match and they have drawn one match.
Leipzig is a good team, even Real Madrid had a hard time playing with them, so they are quite capable of beating Bayer. There is a lot of debate about how successful Bayer can be this season, but I would prefer to wait a few more rounds and see what they can achieve and whether they will lose more points. I think Bayern is strong enough to become champions, in fact they were strong enough last season, but the conflicts between the players and Tuchel made it impossible. Now it seems that everything is more or less in order, so Kompany has a very good chance to make Bayern champions.
