Sunderland boss Roy Keane is confident Greg Halford will prove his worth in the Premiership.

Halford has struggled since his move from Reading and was sent-off in Saturday's 1-1 draw at Fulham.

Keane said: "It has been a difficult start for lots of people, but it comes down to the player.

"Greg showed good attitude. He kept getting into forward positions and if you want to be a top player, you have got to be willing to keep getting there, and I admire him for that."
