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.
Dortmund in the game against PSG had an epic performance and I think even fans of Dortmund couldn't imagine seeing their team winning the semi-final match against PSG while their teams don't have a good place in the Bundesliga table and this can't be easy for this team to be in the final match of the Champions League.
However, they were playing at Signal Iduna Park and Dortmund had many fans watching this match which helped the team.
Now they should focus on both the Bundesliga and Champions League and hope to see Leipzig lose some points and let them take their place in the Bundesliga table.
I feel you on Dortmund's win over PSG. Those guys came out swinging, yeah? It's wild how their Bundesliga form doesn't always translate. Signal Iduna Park though; that crowd is pure fuel. It's a different beast. Now, their season's still a mess. Hoping for Leipzig to slip up is...well, it's a long shot. But hey, this IS soccer. Chaos happens. Dortmund, when they click, they can shock anyone. PSG proves that. My point is, they're a dangerous squad on the right night. They're not just in the Champions League for show, even if PSG has more knockout stage experience. We've seen PSG choke before, just look at their first leg this quarter-final. Dortmund's gotta seize that ruthlessness
