The 32-year-old will join an elite band of players to have made a century of England appearances if he takes to the field in next Wednesday's friendly at Wembley.
Beckham told BBC World: "I'm as fit as I can be. I'm fit and sharp and I'm ready to be selected."
Only Peter Shilton, Sir Bobby Moore, Sir Bobby Charlton and Billy Wright have made a century of England appearances.
"Hopefully I've worked hard enough this month to get myself picked in the squad," Beckham said.
"I have been training with one of the fittest teams in Europe, I've done everything possible to be fit and I am without doubt ready for it, but it's out of my hands now."
Of Capello's first match in charge, Beckham added: "It's an exciting time for English football and it's special to have someone of his pedigree in charge of the game."
