However, it is quite reasonable as you say that if we look back at Dortmund's last few matches I think there is absolutely nothing satisfying about their performance, very different from usual. The draws against Mainz and Augsburg are a hot topic of conversation where both of these teams are far below Dortmund but Dortmund can only get a draw in both of these matches. So I think it's only natural that there are some speculations and assumptions that doubt Dortmund in the match against Darmstadt, unexpected results or even worse than the previous two matches are still possible.
Dortmund appeared not good in the last few matches. They have only been able to win one of the last five matches. I don't know what makes their performance appear quite bad this season. But I think Dortmund must really struggle to improve their ranking. Currently many are talking about Ajax at Eredivise who is able to rise from adversity. I hope Dortmund will also be able to appear quite good to get a place in the Champions League.
Ajax were in last place in the standings not too long ago, but now they are in fifth place. But there is much more competition in the Bundesliga. Probably Dortmund spent a lot of energy in the group stage of the Champions League, so they performed poorly in the Bundesliga. But their position in the standings is still good.
