The former Leeds United man has been outstanding for Villa this season.
"I'd love him to get called up, even if he just got into the squad," said the Scot, "for a young player when you're playing ever so well and you keep getting overlooked it's hard.
"Whether he's got aspirations to do it, you're probably better off asking Fabian yourself. But from my point of view I'd love it.
"I want him to get to a World Cup because I know from own experience it's a great tournament. You might only get one throw of the dice at it, the World Cup. You just don't know and the opportunity's there.
"He's been excellent this year. He grew into it towards the end of last season, like everybody, and he's carried on."
