He's always been a leader throughout the youth teams, definitely a confident guy. That's a good trait to have for any keeper. You can see it here for example in his post-match interview:
There is talk of him being #2 for next season but that is a big step up to be the first cover for Gigi. Perhaps he would be better given a chance on loan. I think after Donnarumma and Meret there is this guy, not many weaknesses in his game.
