The defender told manutd.com: "Tom, or 'Chunks' as we call him, has probably been the most improved player of anyone over the last year or two. He really surprised me when I came back from Sunderland with his improvement.
"He was rewarded with a spot on the South Africa tour and when he came on for his debut, he didn't look out of place. He got a goal for himself as well, which will have done wonders for his confidence. When he was younger he was always very small, but he's shot up now and filled out a bit as well and he's a very good footballer as well. I have no idea why everyone calls him 'Chunks', but that's what he's been called as long as I've been here."
