Ledley King has cast doubts over whether he could switch to a midfield role in England's final World Cup warm-up game against Japan because of the extra demands it would place on his knee.
The Tottenham defender marked his first international for three years by grabbing the opening goal in England's 3-1 win over Mexico at Wembley on Monday evening.
There has been speculation he could be employed by Fabio Capello in a holding position in front of the back four in Graz.
But King is unsure whether his knee - he is unable to train between matches - would stand up to the rigours of such a switch.
He said: "Do I fancy a holding midfield role on Sunday? I don't know, I am not sure about that. A lot has changed since I last played there.
"With not training, midfield is a different role, it is different on the body. I've got kind of used to playing at the back and adapting to certain movements.
"Midfield would be a totally different role so we will have to wait and see, one I'm willing to try if it was the case and I was asked by the manager."
