Hutton, who signed a three-year deal at the club this week, said Keane's famous passion is vital.
"He can be occasionally volcanic, is that threat useful? I think so, it keeps you on your toes, but you want to perform for yourself," he said.
"You know he'll give you the shot you need to perform and spur you on, it's not a negative thing.
"You just have to look at his career, if there's anything you need to ask he's the man to go to. Just to have a man like that in your corner is unbelievable.
"He's passionate about the game, so if anyone needs to say anything about the game he's the man to do it."
