That game is hard. PSG had an excellent season and Real Madrid changed a bit comparing to the previous season. I would say PSG looks favourite to me before the changes in Real Madrid and right now I still think they can make it.
The match between PSG and Real Madrid in the final round will certainly feel like the final round, indeed PSG has been more consistent so far and PSG is in a high winning spirit mode. Moreover, the competition between the two is not only in the game but there are several things that make them compete in several things. For example, when it comes to Mbappe to Real Madrid, even now RMA is eyeing Vintinha, and PSG's strong desire to eliminate Real Madrid wherever it is.
Yes, we are going to face another final before seeing the final. But it will not be easy for Real Madrid to beat PSG. Because both teams are very good. On this side, 2 players of PSG got red cards, which is why PSG is far behind. On the other side, Real Madrid and 1 player got red cards.
But it is not possible to say who will win. Every time there is a fear of who will win and some assumptions can be made. But the Real Madrid and PSG game is not possible to say what will happen.
