He's average at best. And he's 25 so not even that young that you think he can iron out his rawness.
Utterly hopeless if he doesn't have acres of space to run into. I have seen him score a few nice goals for Milan, but they all had one thing in common - he was able to run through the pitch and outpace others. Zero IQ, not great on the ball, poor decision-making, can't cross etc.
Once his speed goes he will be lucky to get a game in serie B. Neto should be starting.
Leao and Felix are examples of players rated by hype rather than substance. For some fans someone running fast and attacking a full-back is enough to rate them as a superstar.
