David Beckham concedes he faces an uphill battle to win a coveted 100th England cap against France on 26 March.
England boss Fabio Capello did not pick Beckham, 32, for this month's win over Switzerland and he fears a lack of fitness could see him sidelined again.
"I've no match fitness," said Beckham, who plays for LA Galaxy in Korea on Saturday. "All I've done is training.
"I would love to reach the 100 caps, but I have to be physically ready to be part of the team."
The former England captain played under Capello at Real Madrid and, though the Italian says Beckham is still part of his plans, the midfielder accepts his selection policy.
"I've played for Capello before, and he's a great manager," Beckham said.
I don't think we have seen the last of David Beckham
"He is a manager that will pick players that are fit enough. I understand he selected others who played more games."
