Hull manager Bruce said Moyes, the early favourite to replace Ferguson, had done well enough at Goodison Park to be able to take on the United job.
"He's cut out of the same cloth (as Ferguson) so it wouldn't surprise me," Bruce told Sky Sports News.
"It doesn't seem quite right that Fergie won't be in charge of Manchester United any more. It's impossible to copy somebody like him.
"He will treat the groundsman just as well as he will treat his star centre-forward. He's got a fantastic humility about him, for all that he's achieved."
