Hutchinson told goldenpanda: "He's scored more Serie A goals than Denis Law now, breaking his record at the weekend.
"He's playing in his best position. The biggest compliment is that his manager, especially someone like Antonio Conte, who's normally been quite rigid in his playing style, he's gone from a back three to a back four to accommodate Scott McTominay. I mean, that's a massive compliment when a manager changes your complete style and philosophy for one player.
"So [he is] massively underrated. Steve Clarke puts him in his best position for Scotland. That's why he scores goals when he's playing for the national side. Conte's doing the same thing and now what you've got is you've got a No.8, No.10 that's got freedom to get in the box and score goals.
"That's what he's good at. He's not a No. 6. He's not a deep-lying midfield player. He can play at eight, of course, he can do it, but he needs the license to go forward. He's one of those sorts of players where you build a side around him because he will get and he should be getting double figures every season."
