"Now I go to watch a basketball game and, when you are watching athletes play at the top of their game, for me it gives me that itch again," he said in a documentary to be broadcast by the BBC on Monday.
"I want to be back in the game then and I start thinking to myself, 'Could I play again? Could I go back? Could I come out of retirement and start playing again?'"
Beckham, 39, called time on his playing career last year after a brief spell with French giants Paris Saint-Germain.
The former midfielder is currently working to launch a Major League Soccer team in Miami and he suggested that he might consider turning out for the team.
"There's never been a player-owner, but maybe?" said the former Manchester United, Real Madrid, Los Angeles Galaxy and AC Milan player.
The documentary, David Beckham: Into The Unknown, charts an 800-mile (1,287-kilometre) journey that he made into the Amazon rainforest, ahead of this month's World Cup in Brazil.
