The Manchester United midfielders comments come as the football world is split over recent diving allegations.
“I’d play honestly every time I play,” said the Scotland skipper.
“Sometimes a keeper can obstruct you and you stumble and fall and there is a difference between that and diving.
“That’s where there is not a clear, defined line about how the referee perceives it.
“But if he doesn’t touch me, I’m not going down. That’s just the way it is.”
