The 36-year old midfielder has a clause in his MLS contract which allows him to own a club in North America’s domestic league but it can only kick in once he stops playing.
Garber said that once Beckham’s playing career is over, then they will sit down and work out exactly where he is going to make an investment.
“David has the option for our 20th team and that option can’t be exercised until after 2011 or after he stops playing,” Garber said.
“So we’ve got some time to figure this one out.”
Beckham has been most heavily linked with incoming franchise New York Cosmos whilst potential teams from Miami, San Diego, Oklahoma and Cincinatti are also a chance of having the former Manchester United and Real Madrid star involved.
