David James insists Fabio Capello has got every member of his squad ready for World Cup duty.
England finalised their plans for South Africa on Tuesday, with the final 23-man party put in place.
The Three Lions are among the favourites to take the trophy this summer and expectations are as high as ever among a demanding public.
Performances in warm-up matches against Mexico and Japan have done little to inspire confidence, but victories have been taken from both fixtures.
Capello is keeping his cards close to his chest regarding who will make the starting XI for England's opener against the United States on 12th June, with the Italian still having plenty of food for thought.
Veteran shot-stopper James is among those hoping to be given the nod, having returned to the team to earn his 50th cap against Japan on Sunday, but he believes all of those in the reckoning are capable of making their mark and doing their country proud.
He said: "It's only taken 13 years to get to 50 caps so it was well worth the wait, I'm sure!
"It's been a long time between 49 and 50 caps and it's been a long season with injuries and whatever else (at Portsmouth).
"Just to start against Japan was very nice, my first start in over a year, so I was very happy.
"Have I staked your claim to be England's number one? We'll see what happens with the selection.
"Joe Hart played well during the second half (against Japan) and the squad is looking all right."
James added: "I get asked if not knowing who is number one makes it difficult in terms of preparation but we're always prepared.
"It makes no odds to me. We'll be prepared for the first game against the USA and selection numerically doesn't necessarily determine who is going to be starting the match.
"The first 11 (in terms of numbers one to 11 in the squad list) may not be the starting 11.
"The way Fabio Capello sorts things out I'm certain we'll be in the best shape we can.
"I'm hoping it's going to be me chosen, of course, but it's about the squad and everyone will be prepared if called upon for the first game."
