"People would be amazed by the amount of work and conditioning Phil has put in to get himself right," said Moyes.
"He continually works hard. He is in every morning at 8.30am, he doesn't leave until late. The rehabilitation work he puts himself through - never at any stage does he complain.
"He just continually pushed himself to try and get back. The biggest impact that it should have on everyone is the manner of what he has done.
"They might not say it but I think they would all have to have admiration for how he continually prepares himself and the way he goes about playing.
"It has helped him recover from this injury. We will have to look after him. He has had a bit of cartilage taken away, so we will have to be careful that it is not bone on bone in his knee. I might need to try to calm him down a bit!"
