I think Bayer will have a completely different season, first of all because of the heavy workload on the players in the Champions League, to some extent because the Champions League will use a new format, which will increase the number of games. In the next round they will go to visit Hoffenheim, and after that the Champions League matches will begin, and we will have to see how the results in the Bundesliga can change from the end of September. It seems to me that Bayern is more accustomed to this regime, so they will cope with it better.
Leverkusen after losing in the last match, this proves that Bayern Munich will undergo a different season from the previous season. In addition to the additional match schedule due to the new Champions League format, Leverkusen also has a heavy burden because winning the title by defending the title is something different because usually defending the title is more difficult than pursuing the title. I mean Xabi Alanso must immediately evaluate the previous performance and make the defeat a good sign to continue to improve the team to be even better.
Leverkusen must immediately rise when facing Hoffenheim later, especially on paper Leverkusen is superior to Hoffenheim so this will be easier to win. Because this victory is also important as capital to increase self-confidence before facing Feyenoord in the Champions League.
