Beckham was surprisingly left out of the squad by Stuart Pearce.
“Everybody knows how proud I am to represent my country and to do it in my home town on such a big stage would have been incredible,” Beckham told Sky Sports News.
“So of course yeah I am disappointed.
“I am very proud to be an ambassador and I have been for the years that has led up to this.
“Getting the Olympics was one of the proudest moments to be involved in with the bid team. It was an incredible moment.
“And then all the talk of me possibly performing in the Olympics would have been a very proud moment for me.”
