We'll get a big keeper to replace Buffon, a guarantee, unless one of the random kids just explodes. If for example Scuffet is the same sort of level as De Gea was aged 20 it would be interesting to see if we would pay €30m to have someone that age start for us, because keepers that age will make mistakes no matter the talent.
I don't remember many, tbh He was something like 23 then though. He won the UEFA Cup aged something like 20-21. He was also Serie A keeper of the year that season.
Basically Gigi is a monster and it's unfair to compare anyone to him.
