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.
Because when Mbappe was there, they trusted him to get them the win, but when he isn't, Dembele knew he had to show up or they would replace him with someone better. So now everyone plays better, because they all know they can't trust Mbappe to help them win anymore. PSG should be able to win this game normally, but I really can't promise anything, it's a risk.
