The 38-year-old, one of three overage players, will be making his first appearance at a major tournament this summer after a lengthy and hugely successful club career at Manchester United.
The highly-decorated Welshman is proud to be representing Britain at the Games and believes he may well soon have another medal to add to his collection.
"Obviously it is a tremendous honour to be part of the Olympics," he said. "Stuart (Pearce) has obviously given me the captaincy, which is even better so I am really looking forward to it.
"It is a unique experience and one from the start that I wanted to be part of when I got the opportunity.
"I think it just got more and more exciting as the Games got nearer and then when the squads were announced I was obviously really, really proud to be involved.
"We hope we can get gold. That is what the players are hoping for.
"The players are winners and want to do well. You want that gold medal.
"It is going to be tough because a lot of the other nations have picked good players and have got good team.
"It is going to be tough, but we have a good chance."
