Dortmund are losing their title chance in the Bundesliga little by little every week. They still would be able to qualify for the Champions League easily though but maybe they would start focusing on the Europa League more to at least win a title this season. And this would lead them to demolish Rangers in their matchup. This would be a great start and they would threaten the other teams like this also.
Right now the chance for dormund to win the bundesliga title is almost impossible, as well as the champion league trophy, their chances of winning the champion have been tightly closed, but currently dortmund still have two competitive titles that they might be able to win, one of which is the DFB trophy which may be relatively easy for them to get, while for the european league cup, i'm a little doubtful if dortmund can get it, because even though the UEFA league is the european league second caste competition, but still there will be tough competition in the match and now some big teams like barcelona, napoli, atlanta and PSV of course also target to be able to get a trophy.
The Dortmund team should now aim for the Europa League title. If Haaland decides to stay in Dortmund without changing teams in the winter transfer window. Then Dortmund might win the Europa League title. Because I think Barcelona, Napoli and Atlanta are the strongest teams here. Napoli or Barcelona will be eliminated in the first round. Moreover, Napoli and Barcelona are not in a good position now. So I think the Atlanta team is the only strong opponent of the Dortmund team. If Dortmund can perform well against Atalanta. Then maybe they can win the title.
