He has high hopes for the player the Ibrox club valued at £5million and is delighted to have landed the Scotland star for free.
Moyes told the Sunday Mail: "From what I've seen of him in the past, his personality fits in well with us. It fits in with what we've got and what we like to bring in.
"He gets on well with the group. He's a worker and a competitor. He can score goals and that's something we badly need. I hope he'll score goals for me.
"Really, his all-round attributes look as if he will be well suited to this club and the demands we have here.
"We're still waiting on him to totally recover from his knee injury. We won't push him - we'll be gentle and considerate as he's missed nine months of football."
