Moyes believes his Holland striker could play a part in United's Christmas programme, although the Boxing Day fixture against Hull is a few days too early.
"Robin is progressing, coming on," said Moyes. "He's doing quite well. He's feeling quite good, but we've got to make sure.
"He has had a similar injury at Arsenal on his thigh, so it's something we have to make sure that wouldn't be repeated. We will try to do it steadily."
