I'm calling it now.
The final will be between PSG and Fluminense with over 3.5 goals , both teams to score and PSG lifting the trophy. At least this is how I see the situation because Real is clearly not stronger than current form of PSG and Fluminense played a great football overall while Chelsea had ups and downs until here. However , I can see extra time and penalties in one of the semi-finals.
This is football where anything is possible, This competition has been full of surprises where the unexpected happens to be the outcome. I wouldn't disagree with your prediction about PSG and fluminense making it to the finals because for the infact that they have made this far shows that there are strong. Just like I have said earlier that this competition is full of unexpected outcomes,you will be Surprise that Chelsea will defeat fluminense and Paris saints Germain will be eliminated by Real Madrid,it's possible for this particular outcome to happen where Chelsea and Real Madrid will make it to Final. Don't underestimate Chelsea and Real Madrid in this Competition, the both clubs are very good in winning trophies.
