Terry told BBC Radio Five's Sportsweek programme: "David is a credit to himself and what he has done is exceptional. If he is going to start or come on, he fully deserves to wear that England armband.
"I am very nervous about joining up with the squad and certainly don't expect to be captain. I wish to continue as England captain and fingers crossed I can do that but if not I will respect Mr Capello's decision."
And when asked whether he thought Beckham would win his century of caps, Terry replied: "I certainly hope he will. He's proved his fitness and he was really disappointed not be involved in the last game.
"The whole country is hoping he gets his 100th cap, because if anyone deserves it David Beckham does."
