Freiburg will face a slightly tougher opponent than Dortmund so the chances of Freiburg winning are not certain because Frankfurt are also trying to maintain their position in the Champions League places. And if one of them loses this weekend it will certainly give Dortmund a big advantage if Dortmund can continue their winning run at home to Holstein Kiel which is a weak team that Dortmund can easily beat. I hope Dortmund can return to the UCL next season with the current coach so Dortmund must try to win one of the UCL places this season.
Dortmund will try to qualify for the Champions League. Maybe Dortmund will win against Holstein Kiel. But whether Dortmund can stay in the top four of the table will depend on Freiburg's performance. If Freiburg can win against Frankfurt, Dortmund will remain in fifth place in the table. And if Freiburg vs Frankfurt match is drawn or Frankfurt can win, Dortmund will be able to occupy fourth place in the table. I am mainly waiting for the result of Frankfurt vs Freiburg match. Dortmund will win against Holstein Kiel, it is certain.
