Leeds and Burney have stepped up the pressure on the Premier League to investigate Everton's finances, writing to the governing body to ask that they ensure Everton retain all the relevant financial information that would be pertinent to an inquiry.
The two clubs, who are locked in a fight to stay in the Premier League on Sunday, have teamed up to push the Premier League to look into Everton's finances and establish an independent commission in the next five weeks to establish whether they have broken Premier League financial rules.
Leeds and Burnley have sent the second letter this week to ensure the Premier League are mindful that all the records, including phone messages and emails, that might be needed are retained.
