Ledley King believes he can replace Rio Ferdinand in England's defence and play a full part in the World Cup.

With captain Ferdinand ruled out of the tournament with a knee injury, King looks set to partner John Terry, ahead of Jamie Carragher, at the back.

That could mean playing as many as seven games in the month of the World Cup - something which is a big ask for a player who finds training difficult because of his own chronic knee injury.

King, though, is confident he can play a full part in England's campaign.

''I like to believe so,'' he said. ''The medical team, the facilities are second to none.

''I believe with the right help and support I can do that.

''The medical team, the manager have allowed me to do what I normally do. I couldn't ask for any more than that.''

England play a friendly against local side Platinum All-Stars on Monday, five days ahead of their tournament opener against the USA, with King likely to play at least 45 minutes.

''I've shown this season I can play games in quick succession,'' said King, who stepped up his activities in the run-in of Tottenham's Premier League campaign this term.

''Monday to Saturday shouldn't be a problem for me," he said.

''However many minutes I get I believe I will be ready if needed on Saturday.''

King believes he and Terry can form a solid partnership for England.

''I've known John for a long time. He's a great communicator on the pitch and that's what you need,'' he said.

''It is difficult. We're not going to have much time to for it regardless of me training once or twice a week.

''Communication is key and if that's good, we have a good chance.''
