The two remaining matches are not too tough for Dortmund, on paper Mainz and Darmstadt can be beaten easily if you look at the difference in position in the standings list. Dortmund who is trying to finish in fourth place, must take advantage of these two matches to achieve victory. Edin Terzic certainly doesn't want to take risks because there are still much more important matches after successfully leading Dortmund to the UCL final.
This season passed in an extraordinary way, Dortmund were always unable to compete in the Bundesliga but were able to appear in the UCL final. It must be admitted that they are not very good in the Bundesliga, there are always obstacles that make it difficult for Dortmund to win the Bundesliga trophy. Dortmund must win the UCL trophy as an alternative route to appear in the UCL next season if they fail to finish in the top four in the Bundesliga.
Dortmund remaining two games are of course very easy because they will only face the bottom teams of the Bundesliga later, but I think for now Dortmund no longer care about the game and will focus their attention more on the Champions League final later, the games against Mainz and Darmstadt of course no longer affect their qualification to the Champions League next season, Even if these two matches Dortmund suffered a defeat but still they could qualify for the Champions League despite ending the season in 5th place later, currently Dortmund has a gap of 15 points from Frankfurt and with two games remaining it is certainly impossible for Frankfurt to get rid of Dortmund's position in 5th place.
For now I think there is no more importance and also a very important match for Edin Terzic apart from the Champions League final, ending the season with 2, 3, 4 and 5 position for Dortmund this season is no different because indeed they will still be able to qualify for the Champions League next season because indeed the Bundesliga this season gets 5 slots for UCL next season, And maybe even the Bundesliga can send 6 teams to the Champions League next season if Dortmund and Munich win the Champions League this season, but for now what is certain is that the Bundesliga will send 5 of their teams to the Champions League next season because the Bundesliga is one of the two UEFA associations with the highest points coefficient this season.
