"The biggest thing for me is how much he's bought into it with his work ethic. There was a period in the game last weekend when he worked back after about 70 minutes and has done a job for the team. The big thing, for me, is how much of a team player he is being.
"He's in great nick. He looks after himself and had a really good season without injury last year, a clear run that he got good confidence from.
"We did know he had a couple of spells he went through when he didn't score but it happens with forwards at times. Manchester United did the right thing and tried to play him through it.
"Overall, I've been really impressed by his attitude and the way he has gone about his work. He's been great to work with, he really has. I asked him how many medals he'd won and he said one but I saw a glint in his eye to say: 'I need more than one' and so do I!"
