Leverkusen are a very good and strong squad, but even with that, I’m not sure if they can be able to do the same thing they did last season in the Bundesliga, which is the unbeaten record. They can take the trophy, but you see, that unbeaten record is what I doubt because many clubs will come stronger and even do better than what people expected.
But do you know that Leverkusen still have the capacity to repeat the same thing as well they they remain unbeaten this seasons, we all know that there so many clubs that are more strong than leversekun, but not all have strong squad like Bayern leversekun so stated that you didn't have hope for them that they can able to keep a unbeaten record next season i think it's too early to underestimate them; because they might bring a surprise that nobody will expected in next coming season.
Although I know that Bayern Leverkusen are currently one of the best clubs in the Bundesliga apart from Bayern Munich, I can’t still compare Bayern Leverkusen to Bayern Munich just because Bayern Munich experienced a bad performance for one season. They may come back stronger next season, and next season, the Bundesliga will be so competitive.
In terms of counting a clubs that can able to competitive I can't include Bayer Munich with there performance, so in this case there's no way you can compare Bayern Munich to Leverkusen because there performance are different far from each other. But you can only compare other clubs to Bayern Munich, but count out the bayern leversekun from that stage because there no more in the same level.
