With Dortmund winning and Wolfsburg getting a point from leipzig, European positions are determined before the last round tho. Bayern + Leipzig + Dortmund + Wolfsburg to CL. Frankfurt and Leverkusen to EL. There is also a spot for Europa Conference League which will be for the team sitting in the 7th spot, Union? M'Gladbach? Stuttgart? Freiburg?
Obviously 1 spot for the relegation + relegation play-offs have to be determined too in the next round.
I am not so sure about Wolfsburg to be honest, sure German teams have done great specially Bayern which is why we always get Bundesliga with 4 teams to champions league, however that fourth team is rarely any good, it wouldn't really have mattered a lot whoever that team was but at the end of the day Wolfsburg managed achieve it. However even worse is what is going on with both Leipzig and Dortmund, to be more clear what they are going to be missing next year and how they will cope with that.
Dortmund is said to be selling Haaland and Sancho this summer, we do not have confirmation but they are definitely on the block for sure and that means Dortmund, even if spends money, may not be as good next season (probably). On the other hand Leipzig misses their best defender and also the manager that brought them here as well. Both teams will have a big trouble for sure.
