David Beckham insists he can still play for England after his summer move to Los Angeles Galaxy from Real Madrid.
Beckham has been in impressive form for Real Madrid
The former captain, 32, is expected to be recalled when Steve McClaren unveils his squad at noon on Saturday for the matches against Brazil and Estonia.
Beckham was speaking to BBC Radio Five Live in a recorded interview 24 hours before the squad announcement.
The Real Madrid midfielder said: "I'll be a lot fitter (playing in LA), still as fit as I am now, maybe more fit."
He added: "The training will be difficult in America with the humidity so I still feel I'd be able to play for England."
Beckham has not played for England since the World Cup quarter-final defeat against Portugal last June.
However, McClaren is now expected to turn to Beckham for the friendly against Brazil at Wembley on Friday 1 June and the Euro 2008 qualifier in Estonia five days later.
And the midfielder is confident the new challenge of the Major League Soccer (MLS) season will spur him on for future international call-ups.
"The US season is shorter, we only play 30 games a year, so we get more time off," Beckham added as he explained his decision to move to the States.
"I had offers from two big clubs in Italy and offers from clubs in England but I just felt it was the right time to pack up and leave.
"I was honoured to have played for Manchester United for so many years and obviously Real Madrid for four years.
"But I wanted a different challenge and to me the biggest challenge was going to America and playing in the MLS and living a different lifestyle. I'm looking forward to it."
David has never been in such good form either mentally or physically
Madrid coach Fabio Capello
McClaren left Beckham out of his first squad for the friendly against Greece last August but is now set for a dramatic U-turn.
McClaren insisted: "I never said the door was closed. You will see on Saturday what the intentions are.
"I keep my eye on everyone and David is one I said from day one that his form will be monitored."
Beckham has impressed with his return to form for Real and, although he has been limited to playing just three out of their last 10 La Liga matches because of injury and suspension, he has been influential.
The midfielder is expected to play on Saturday when Madrid host Deportivo La Coruna, and, according to Madrid coach Fabio Capello, Beckham is in the "best form of his life".
"I told David the other day that I thought he has never been in such good form either mentally or physically and he agreed with me."
"I can't understand how a player who is playing so well can be left out of any national side," said Capello.
