Usually it would be Bayern Munich vs Dortmund for the tight rivalry.
But for the new season, it will be Bayer Leverkusen vs Bayern Munich.
Seeing the fierce competition between Leverkusen and Bayern Munich last season, we will definitely assume they will compete again next season. Leverkusen is still managed by their great coach Xabi Alonso, while Bayern Munich has got a new coach, but we don't know whether the new coach's skills will be as great as Xabi Alonso ? Bayern Munich's coach is a young coach like Xabi Alonso and they also don't have much experience, but we shouldn't doubt Vincent Kompany before he shows his abilities, even though it's a bit of a problem. But I know that out of the many choices, Bayern Munich has decided to choose Vincent Kompany. Who is knows he can provide what Thomas Tuchel couldn't last season.
It looks like next season the competition will be even fiercer between Dortmund and Bayern Munich with their new coach and they will compete fiercely with Leverkusen in the hunt for the title. I still include Dortmund as a strong candidate to win the title in the Bundesliga even though they sometimes lose to Bayern Munich, but still Dortmund is one of the clubs that Being able to reach the final in the Champions League last season.
