the performances of Freiburg and Frankfurt are much better than Dortmund and I predict that Dortmund will not be able to finish in the top 5 until the end of the season. dortmund is ranked 6th in the bundesliga standings with 25 points, so far dortmund has lost 6 times, and that keeps their ranking from being in the top 5, other news that is not pleasant to hear is that Youssoufa Moukoko intends to leave dortmund, this will definitely add to internal problems for dortmund because bellingham is also reportedly being targeted by another team.
Maybe the two reasons you stated could become a harsh reality for Dortmund this season, but I still don't think that Dortmund will be as weak as you think. Because Dortmund only have to fight for two more positions to be in a better position than now and I don't think it will be as hard for them (other teams) who are fighting for the Bundesliga title like Bayern Munich this season again.
