Sunderland boss Roy Keane is demanding huge money for star striker Kenwyne Jones.

"£12 million? You'd have to double that at least," the Irishman told Setanta Sports. "He can be a top, top striker, one of the best on the world. He's got the potential but potential is one thing and fulfilling it is another.

"That's why we hope we can bring the best out of Kenwyne. He's been a pleasure to work with and I hate to think where we would have been without him."
