Dortmund is actually far from falling into the relegation zone because of the point gap between them and their teams currently in that zone. They may have played poorly in the past and a lot of them already making it look like they can’t stand a chance in the fight for an Europe spot next season. I still think they will want to try as I see their journey in the champions league is already coming to an end. They can at least get a spot in the European competition next season if they try more but I don’t see them in the champions league next season when they get eliminated from the competition now.
You are right. Given their poor performance and lack of consistency, it is unlikely that Dortmund will qualify for Champions League football next season, their struggles in both attack and defense coupled with dropped points against weaker opposition have severely impacted their position in the league table, unless they show a dramatic improvement in forms and results securing a top four finish appears to be out of reach.
