Should the referee have whistled for a foul? That's the big question. I think it's 50-50 if you let 10 referee judge. But PSG needn't let themselves get into that situation, they've had plenty of opportunities in the first half to expand the score, and were much, much better than Madrid. When it went 1-1, Messi should have taken the team by the hand, organize and just make sure you don't get that 2-1. That 1-1 was not necessary either, I also do not understand that keepers want to control the ball perfectly in those situations. Seems much safer to just kick the ball to the center line. They have paid a high price for it, and now that Mbappe is also leaving, it will only become more difficult to win the Champions League.
