Donnarumma is undoubtedly the best goalkeeper and if the list of the five best goalkeepers in the world is made now, then Donnarumma will definitely make his place in that list. However, the bad news for Italy is that this goalkeeper may not be able to provide good service for much longer because he is already old enough. In the selection of goalkeepers, different clubs or different teams always give more importance to young footballers, in that case, in two to three years, this goalkeeper may not be in the same form as before. I wonder what will happen to the Italian team when most of the players who are currently playing for the Italian national team retire. Italy may continue to play football, but we may not see good performances from them.
I don’t really agree with your statement that Donnarumma only has a few years left at his peak. Goalkeepers, unlike strikers or midfielders, usually enjoy a longer peak, often performing well even at 38–40 years old, because their game relies more on experience and decision-making. While it’s possible Donnarumma’s performance may decline, I don’t think it will happen anytime soon. And considering he’s only 26, the Italian national team still has plenty of time before they even need to worry about finding his replacement.
