Portsmouth boss Harry Redknapp hailed Nwankwo Kanu as "amazing" after their victory at Blackburn Rovers.

"I always wanted to keep him," said Redknapp.

"He was looking for a two-year contract and I said one year and an extra year if he played 20 games was a fair deal for him.

"So far he's played nearly every one and scored three goals.

"He's the key for us, a special player. You don't play for AC Milan, Ajax and Arsenal if you're not a top striker. You should see him in training - he can do things with a ball that are just amazing."
