Dortmund was a little lucky to win this first leg match even though if you look at it as a whole PSG's attack was much more dangerous but there was a little luck factor so that Dortmund's goal was not conceded.
For the second leg, Dortmund's percentage of being able to advance to the final is not that big, especially if both teams continue to display the same performance as in the first leg.
Both of them have played very well and in my opinion there is no such thing as luck, it's just that PSG needs to re-evaluate each of their shortcomings so they can improve them in the second leg. Playing at PSG's home ground, of course they will play with enthusiasm against Dortmund because it will be very strange. If two teams from the German Bundesliga meet again in the UCL final like the previous season between Dortmund and Munich, but I'm sure PSG will not let Dortmund win the second leg of the UCL semi-final match again and PSG will surprise Dortmund like they did against Barcelona.
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.
