Dortmund always does the same thing every season, which is where they will focus on one competition, after seeing their chances in the Bundesliga, I think Dortmund only has the chance to play more optimally in the Champions League. It is very unfortunate because in the Bundesliga this season's decline is quite severe, and Sporting chances are much greater to win the match. On the other hand, the play-off round presents Brest vs PSG, a match that is no less interesting. At least this match is an opener to watch before the special match between Man City and Madrid.
Dortmund has a chance of progressing but they'll be facing Sporting that just defeated them the last time the both clubs played. In all games Dortmund has the advantage as they have more wins but their wins weren't as convincing as the last time this two played and sporting won convincingly. Dortmund has improved more in the champions league as they no longer just leave the competition too early and they almost won it the last time that they went to the finals against Real Madrid but they lost. They'll be trying to get to the finals again but I don't think it'll be that possible as the other bigger clubs are playing better this season too to get to the finals and win it.
