I think that Paris has never been in such a favoring draw for the semi final and I am not underestimating Dortmund here,it is just that they have not the same quality players as Paris does and based on this I doubt there will be any surprise regarding which team will qualify for the final.I also think that Paris has the best chances to be crowned as Champions League winners for the first time in their history as they look the team in the better form compared to all the remaining teams in the competition.
I am underestimating Dortmund and say that they are clearly getting a favourable opponent. It would be much much harder to beat Bayern or Real Madrid. Don't get me wrong, Bayern hasn't been great this season and they even lost to Dortmund recently as well so not like Bayern is awesome this year, but it is still Bayern and they are second at Bundesliga whereas Dortmund is like fifth or something.
This means that Bayern and Real Madrid both would be very very tough opponents for PSG. Compared to them Dortmund is much easier and much better, I would rather face them instead, and I believe that we are going to see PSG end up with a win there too, and go to finals. Which would be amazing for them, I think they may win it all this season if they work hard enough.
