Whatever the case, United need to start making those kind of signings. De Ligt and De Jong are two such talents. It's funny, but our best players (Pogba, Martial, Rashford, de Gea) were players playing at age 19 or so. I think Depay was really one of the only ones that failed to live up to the hype while at United, but is now doing fine elsewhere. Same with Zaha. On the other hand, buys like Fellaini, Darmian, Blind, Rojo, Mkhitaryan, etc... have all been underwhelming.
We should be building a young side full of obvious talent.
