Sunderland midfielder Grant Leadbitter admits he was sorry to see Roy Keane leave earlier this season.

Leadbitter told The Sun: "I have a lot of respect for our old boss Roy.

"He was a nice man. He had a positive impact on every player at the club, he had an aura about him - he's Roy Keane!

"Someone like that is always going to be missed. My game improved under him and it continues to - hopefully."
