Dortmund will face Augsburg but it seems they will not play their key players full time because of course they will save energy and ensure the players' performance remains in good condition when the second leg match takes place, because Dortmund only needs to draw to qualify for the UCL final. this season, but PSG will definitely try to score a goal against Dortmund, especially playing in front of all their supporters, of course they want to win and reach the UCL final this season because Mbappe doesn't want his dream of bringing PSG to the UCL final to be buried again because he failed for the umpteenth time. He will definitely try to play as well as possible to score goals and Dortmund must be careful in the second leg.
Dortmund has secured fifth place. They have confirmed their ticket to the European League group stage next season. I don't think Frankfurt will be able to catch up on their points. So as you said Dortmund will not play all their key players in that match. They already have a goal advantage in the first leg so I think Dortmund will not waste this opportunity. But a 1 goal lead doesn't make much difference. PSG will play aggressively to get 1 goal and I think it will not be difficult for them because they will play at home next week.
Wow, the fact is that the Bundesliga also gets five Champions League tickets for next season like Serie A. With factors like this,then eventhough Dortmund only finished in fifth position, but Dortmund has also been confirmed to get a Champion League ticket next season. Soyes, eventhough in the next Bundesliga match that Dortmund will play at homeagainst Augsburg, but I'm sure Dortmund will not maximize their mainplayers to play in this match. Therefore,maybe Dortmund can also only get a draw or maybe lose by Augsburg, who knows. Because ofcourse, Dortmund have been in a very good moment to be able to qualify for the Champions League final and therefore, I am sure Dortmund will really maximize this moment to focus more on the Champions League because anyway,in the Bundesliga standing Dortmund have also been confirmed to get Champions League tickets next season.
