the Dortmund vs Mainz and Munich vs Koln matches will take place at the same time. this will determine who will get the title. Munich and Dortmund must win. this would make it impossible for the two to make a mistake. especially for Dortmund who are one step away from winning the Bundesliga title. they're not going to let him get away with it. drama may ensue, but hopefully not for the hunt in the Bundesliga.
This will be a very hot match because the two teams from Dortmund and Bayern Munich are fighting for their best position in the Bundesliga, so these two teams must win to maintain their positions. Bayern Munich may find it difficult to fight against Koln because Koln has strong enough strength to confront Bayern Munich, while Dortmund might find it easy to win in this match because Mainz has only won once in their last five matches.
Now it only remains to depend on Dortmund I think because Bayern can't do anything but expect them to win in their last match and Dortmund lose their last match.
Bayern released control when they had to lose painfully to Leipzig which made them currently unable to compete apart from having to win and hoping that Dortmund would lose or draw because if that was possible then they could still get the championship but if 3 points come back for Dortmund then Bayern have to say goodbye to their long-held trophy.
Bayern preference was very unstable during the whole season and the actual situation seems very logic, i think the biggest mistake is changing the coach during the season, the administration have a big part of responsibility in this failure in my opinion, they still have a small chance in the last round but i really believe Dortmund will not give up this opportunity
