The basketball star, who owns a stake in Liverpool, in interested in joining the former England captain's efforts to establish an MLS side in Florida
The former England captain, who had the option to purchase a team included in his contract when he signed for Los Angeles Galaxy in 2007, met with league chiefs in October over the possibility of founding a club in Florida.
James, who owns a stake in Liverpool, has revealed he has spoken with Beckham over the prospect of bringing the MLS back to the city and is confident the project could become a huge success.
"There's some interest in both sides," the basketball icon told ESPN.
"David has become a good friend of mine over the last few years and I think it would be great for this city to have a football club, for sure.
"The research is still being made out but I think it can be huge.
"I think this is a great town for soccer. There are a lot of soccer players here. There is a lot of great youth soccer here."
Miami's last MLS franchise folded in 2002, when Miami Fusion were withdrawn from the league after just four seasons.
