Burnley and Leeds have asked the Premier League to ensure none of Everton's financial data from the last three years 'ends up in the North Sea' before any investigation into alleged breaches of financial fair play rules.
The two relegation-threatened clubs have warned they are considering bringing a case against the Goodison Park outfit over whether or not it has broken FFP laws after it recorded loses of £371.8million over the last three years.
Clubs are allowed to make losses no greater than £105m in any three-year period. As a result, Burnley and Leeds have asked the Premier League to write to Everton to tell them they must make available details of every single transaction.
