The former LA Galaxy midfielder has been considering taking ownership of a new Florida club for several months, and has an option to take up ownership of a club in the US league for a $25 million fee.
There is not currently an MLS franchise in Florida, nor any of the closest dozen or so states in the region. The closest clubs to Miami are Houston Dynamo to the west and DC United to the north. The last time the state had any MLS franchises was in 2001, the year both the Fort Lauderdale-based Miami Fusion and the Tampa Bay Mutiny folded.
