MLS commissioner Don Garber has warned David Beckham's Miami franchise could fall through.
Garber says the former Manchester United and Real Madrid star will need to find a stadium -- or no club will be formed in the city.
"I'm neither optimistic (nor) pessimistic," Garber told Reuters.
"It really is a very simple position we are in - if we can't get the right stadium, we can't go to Miami.
"We have been challenged to find a site that we believe will be successful.
"We had two sites on the waterfront. Both were supported by the city mayor and the county mayor, and then we lost that support, so it is clear to me that it is a complicated market in a wide variety of ways."
