David Beckham has hit trouble with his plans for Inter Miami after an environmental analysis has shown the proposed site for the new Major League Soccer stadium is far more toxic than previously expected.
The study shows that arsenic contamination has reached more than twice the legal limit, according to the Miami Herald.
Surface-level soil samples at the Melreese golf course site contained hazardous debris.
More alarmingly, people have played golf on the course for 50 years.
Moreover, almost the entire site near Miami International Airport is contaminated by ash from the long-since shut down municipal incinerator.
Miami Mayor Francis Suarez has revealed the findings could prove extremely costly with the cleanup now set to cost a further $50 million (£41m),
Beckham's lavish project has spiralled to a cost of $1 billion as they bid to revamp the site into a commercial complex alongside the stadium.
The team only has three attached players currently, with Christian Makoun and Argentine pair Julian Carranza and Matias Pellegrini - both out on loan.
The new franchise will join Nashville, Austin and St Louis with MLS expanding to 24 teams.
