Perhaps there is a rational grain in this, Bayer went through this season quite simply without much competition in the Bundesliga, everything may change when they feel pressure every round from the fact that their pursuers will be very close, or even more so if Bayer has to be in the role of a catching up team, which will always be a few points behind Bayern, or even possibly other teams. On the other hand, Bayer managed to keep all the players in the team, they were even able to strengthen some positions, so they have a chance to remain a competitive team, but it all depends on Bayern how they start this season.
We will see how the two teams start next season, because I still think that both teams will still have the strength to be more competitive. Although Leverkusen, who are still able to retain all their players and will also improve several lines which they think are still weak, will be a team to pay more attention to next season after being able to perform so well last season in the Bundesliga. Apart from that, I also want competition in the Bundesliga to become fiercer so that many people are interested in watching all the matches in the Bundesliga next season.
