The 36-year-old’s deal with current club the Los Angeles Galaxy is about to run out and he claimed there has been interest from Barclays Premier League clubs as well as Ligue 1 side Paris St Germain.
His involvement in the British team in next year's Olympics has been mooted as a way to increase interest in the competition. Coach Stuart Pearce has to pick a squad of predominantly U23 players, but can pick three over that age.
Beckham told BBC Sport: “We all dream about it and we all think about it. If it happens, I’ll be honoured.
"People have been saying [I am too old] for the last 10 or 15 years and I've still continued to play for my country.
"Right now, I feel fit and still love playing, so I'm not finishing yet."
With his LA Galaxy contract almost up, attention has turned to his next destination whether that be in Europe or staying in the United States. Beckham is likely to buy a team in the United States, suggesting any move back to Europe is unlikely.
He added: "I have the option and it's something I probably will do. Obviously I have to wait until I finish playing.
"I want to be part of something that is going to grow and I believe that this sport is going to grow."
