Leao proved the matchwinner against Lazio on the weekend.
Shevchenko told Tuttosport: "He's not really a centre forward, he's a winger.
"But if you keep the block a little lower, so as to exploit his best qualities and free up his runs, Rafa has the qualities to do it, and well: when he has space up front, he burns everything with speed. Right now the results are positive: Leao is scoring and learning a new role.
"But it won't always be easy: as a centre forward you have to know how to strike in every situation."
Asked if Leao could find a place in his great Milan team, Sheva added: : "Yes. I don't know if he'd have been a starter, but he definitely would have had a place because he's a striker with unique characteristics."
