Portsmouth boss Harry Redknapp admits Sunderland star Kenwyne Jones has come on leaps and bounds since he worked with him at Southampton.

"He's a fantastic athlete with a great leap - and he caused us problems up there. I've seen him batter defenders this season," said Redknapp.

"At one time he needed to be more aggressive, and it seems like the penny is dropping.

"He seemed too relaxed at times with that typical West Indian style, but he has pushed on.

"Roy Keane has got the best out of him."
