In theory, Leverkusen will not be able to compete with Bayern Munich next season especially because Bayern Munich and Kompany already have solid chemistry. However, I think Leverkusen management is aware of that, so being able to finish in the top 3 for Leverkusen is an extraordinary achievement for Ten Hag. So if I predict Bayern Munich's competitor next season in the Bundesliga trophy fight is Dortmund, because recently Dortmund has been on the rise after firing Nuri Sahin.
I don't want to speak ill about Erik ten Hag in his new club and projecting right now what the season will look like as of next season. The new coach isn't as worse as people conclude while he was at Manchester United, if he is capable of retaining another Champions League entry then it is a job well done coaching
the players through out the season. All that is required from Leverkusen is
not to end atavoiding the bottom table, for the worse performance
they are expected to finish top four, since the title will be out of reach.
Kompany is prepared to compete for another title, warming his players in the Club World Cup and perfecting his style, Dortmund doing the same thing, Bayern Munich and Dortmund are the ones contending for the title next season, Leverkusen are not having chances of ending as a runner up for the title.
