Stoke's supporters were on his back earlier in the contest, even though when he did go to ground it was with good reason.
And Moyes feels his behaviour was impeccable.
"I have spoken to Ashley and I have said, make sure you do everything right. Tonight he did," said the Scot.
"He got kicked a few times and he went down, but he got back up and got on with it.
"He has shown he can come in and make an impact. That is what I need.
"We have got a lot of competition in wide areas at Manchester United, and a lot of players we can select from.
"If you want to get regular outings you need to score and you need to play well."
