Portsmouth goalkeeper David James has no concerns over fitness threats from England boss Fabio Capello.

Capello wants to take the Portsmouth goalkeeper to South Africa next summer but will not take a risk on the 39-year-old if he is still struggling with the knee problem which has troubled him for much of this season.

James told the Daily Mail: "By the time England play again in March my left knee will be fine,' said James. 'I see it as a chance to win my 50th cap, something I'd love to do at Wembley, and if I'm selected I will be fully fit.

"I realised I was going to be out for a while after the shoulder surgery in the summer so I decided to get it cleaned up at the same time. It was just a case of getting a bit of cartilage trimmed. Pretty minor stuff.

"The shoulder recovered much quicker than the doctors expected and the knee seemed to feel fine, too. But I aggravated it a bit in a goal-kicking session and I have had to be a bit careful with it since.

"I can see why the manager might be a bit worried but it's not strictly true that I can't train for two days after every game. I just have a programme in place for now that is designed to allow the knee time to make a full recovery and it means I don't do any goalkeeping training on a Monday. I just go in the gym and do conditioning work before returning to goalkeeping work the next day.

"But if truth be told I've not done much goalkeeping work on a Monday since I joined Portsmouth. When I first arrived I lived in Devon and Harry Redknapp would allow me to do stuff on my own at home on a Monday."
