Ledley is set to make his first England start in the friendly against Portugal tonight following his late call up.
He is likely to line-up alongside Gareth Southgate in central defence in Faro even though he's excelled in a new midfield role at Spurs this season.
Club captain Jamie, capped 17 times by England, explained: "Ledley's form has been great this season and one thing in his favour is that he can play in different positions.
"He's like Jamie Carragher at Liverpool who can play centre-half, left-back, right-back, midfield - Ledley can do the same and you need players like that especially when you come into a squad situation.
"He deserves to be there on form. He has such good feet, is skilful and quick and he's impressed in midfield.
"I think you could play him anywhere, he's one of those lads with good ability and confidence on the ball and that helps so much."
Jamie suggested if Ledley takes his chance tonight it could help him force his way into Sven Goran Eriksson's plans for Euro 2004 this summer.
He added: "A lot of chances come up this way when you get drafted into a squad and perhaps someone like Ledley might go in and play well. Then he stakes his claim for a place.
"It gives you a lot of confidence when you are called into the England squad, it's an achievement for him and hopefully he'll do well and stay in there."
Jamie Redknapp believes Ledley King's versatility can only help as he bids for a place in England's Euro 2004 squad.
