Tottenham manager Harry Redknapp has admitted he is uncertain how long Ledley King will be able to continue playing as a degenerative knee problem continues to affect his ability to train.

King, 30, has been at Spurs his entire career and is club captain – but due to his knee injury he is unable to train regularly.

The centre back was named among the substitutes for Tottenham’s 0-0 Champions League draw with Milan and it was the first time he has featured in a matchday squad since October 16.

King has played just four games this season and has been suffering with a groin injury that Redknapp believes can be attributed to his restricted training regime.

“You have to train,” Redknapp said. “You can’t just come on Saturdays and expect to be the best player. Ledley has got away with not training all week and you can’t do that for long. I think now he’s finding it more difficult, as suddenly he’s picked up a few more injuries.

“He’s got a problem with his groin and we took a gamble with him [against Milan]. We just keep our fingers crossed for him and Jonathan Woodgate because they’re fantastic centre halves. We’re lucky that Michael Dawson has been brilliant and William Gallas has done a great job for us as well.”
