Barcola, Kvara and Dembele has been amazing all season long and I am suspecting they are going to be great on this game as well. Barcola isn't as good as Mbappe of course, but when they had three players who play great together, instead of one superstar, everyone got better. Look at Dembele for example, he wasn't this good last season and he is great this season.
Dembele performance was fluctuating a lot in Barcelona then he moved to Paris Saint-Germain and started to improve and gets his form back. Of course all the players you cited aren't in the level of Mbappe even though he wasn't in his best form with Real Madrid especially in the beginning of the season. I think that Kylian Mbappe is jealous that he isn't assisting PSG in what should be their first UEFA Champions League title, hopefully
He was very well-trained in Luiq Enrique and PSG. Although PSG is very good at attacking in the front, they will not be able to easily open up Inter's good defense. I expect a match worthy of the final.
