This guy is worthy of being the best player performer in both the first and second leg. On the 1st leg, Donnaruma has several times saved his goal from Martinelli's shooting, this is an insane save that can be made by goal goalkeeper who has good instinct. On the 2nd leg, he did it again and made Arsenal players frustrated. I think on the final next, if Inter Milan is unable to complete 90 minutes + additional time, PSG will become the champion with a Penalty shootout.
Inter Milan must anticipate this player. He is from Italy who more understands the Italian player characteristics. he will make a surprise, and become the hero for PSG.
No doubt about ability of Donnaruma as he has shown his saving ability and strong mentality in his career even when he was very young in AC Milan, and later in big tournaments like Euro 2020 when he won it with Italy after a penalty shootout in final match against England.
Sommer is less famous than Donnaruma and Inter Milan is his first big club but he already shown his ability in World Cup and Euro tournaments with his national team many times.
