The LA Galaxy man was omitted from the squad by manager Stuart Pearce with the three over-age slots going to Ryan Giggs, Craig Bellamy and Micah Richards instead, a decision that Bale was not expecting.

"I was very surprised," Bale told reporters on Sunday.
"I think he's done a lot to get the Olympics to London. But after that he’s a great player, he’s been playing well for LA Galaxy, and I think pretty much the whole nation’s a bit disappointed he wasn’t in the team."
Bale and his Tottenham team-mates are currently in Los Angeles preparing for a friendly with the Galaxy at the Home Depot Center.
The Welshman himself was expected to represent Team GB at the Olympics but a back injury means that, like Beckham, he will miss the tournament.
However, whilst he will not be participating as an athlete, Bale is still looking forward to attending the London Games as a spectator.
"It’ll be an amazing experience to have it in our home city, and hopefully I’ll be able to go and watch one or two events and it’ll be very exciting," Bale said.
Tottenham move on to Baltimore to take on Liverpool on July 28, before concluding their US tour with a match against the New York Red Bulls at Red Bull Arena on July 31.
