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.
It would be great if in the final game on Saturday there would be many matches that ended unexpectedly, where Dortmund lost but Bayern were only able to draw, or Dortmund drew and Bayern won so goal difference will determine who is the winner. If Dortmund are champions it's good to get rid of a bit of boredom because seeing Bayern Munich dominate the league most of the time, but next season is very certain for Bayern Munich who become Bundesliga champions and usually they will appear stronger when they failed to win the previous season.
Dortmund had quite an advantage over their opponents who only played with 10 players after the 38' round because in the second half they were able to maximize the imbalance in the opposing squad by scoring 3 goals because it would have been stupid if they failed, especially since they had seen the results of Munich losing to Leipzig so gave Dortmund the opportunity to take over the table, and they did it. In the last game against Mainz, Dortmund had to win because if it was a draw and Munich won then Munich would be the champions, Dortmund cannot be careless in this last match because the opportunities they have now could be wasted.
Union Berlin and Freiburg will fight for the final spot in the champions league, but Union Berlin has more chances because they will have home games and an advantage on goal difference because if both teams win then Union Berlin will be in fourth place and Freiburg will have to be satisfied with the league Europe.
