Kanu has had an instant impact at new club Portsmouth

English side Portsmouth have shot down reports that striker Nwankwo Kanu is set to join South Africa's Mamelodi Sundowns.

The Nigerian has been a revelation at the Premiership club, scoring five goals in seven games after signing a one-year deal on a free transfer from West Brom in August.

The 30-year-old is reported to have had talks with Sundowns officials in South Africa, where the Super Eagles were camping ahead Sunday's Nations Cup qualifier Lesotho.

But Portsmouth manager Harry Redknapp said: "There is no way we would want to let him go.

"He has signed for a year and done really well for us, scoring five goals and really working hard.

"I said to him when he signed that we would wait until we get to January and then talk about signing for another year.

"If he continues to do well and play like he has we could well extend his deal.

Redknapp is delighted with Kanu so far.

"He has shown a lot of magic for us - even out on the training pitch where the twists and turns he does threaten to damage other players' cartilages and ligaments. He is a class act.

"People warned me off signing him at first, but coach Bryan Robson told me he was the hardest trainer at West Brom and wanted him to stay.

"He has been a terrific free signing for us."
