"Robin will be back, involved somewhere. He trained today and is fit. But we'll have to see exactly where he is," Moyes told reporters.
Moyes added of midfielder Tom Cleverley: "Tom has done a bit of training today as well.
"He is not too serious. He rocked his knee in training and we were a bit worried.
"But he has had no reaction. He has done some training today and he will not be too far away tomorrow as well."
