Bayern had a phenomenal start, but now that they have 2 points in 3 games (Bayer, Aston Villa, Eintracht) I think we can admit that they are not as strong as they seemed at first. They had 3 serious opponents and they got 2 points. I am happy about this in the sense that we will most likely see an interesting competitive season in the Bundesliga again and not boring dominance of Bayern.
Many neutral Bundesliga fans would be happy if the trophy race this season is competitive, regardless of who ends up winning it. Bayern Munich, who have looked unstable in the last 3 matches, in my opinion still have a better chance than the other 19 contestants. Of course it would be boring if Kompany squad eventually dominated the Bundesliga again, but for now, the fact is that they tend to be more favored.
Leverkusen, Dortmund, Leipzig actually also have the same chance, but they have to work extra hard to stay undefeated in the future, so they have the opportunity to overtake Bayern Munich at the top of the standings. It must be admitted, it is not an easy job, it takes a lot of luck to be able to win the trophy, when Bayern Munich performance is good.
Meanwhile, Leverkusen as the defending champion also looks to be experiencing unstable performance, maybe this is influenced by the pressure they get when playing in the Champions League.
