Bristol City owner Steve Lansdown will attend a meeting in a fortnight alongside representatives from the Championship's 23 other clubs with the subject of Financial Fair Play high on the agenda.
The Telegraph have reported Middlesbrough owner Steve Gibson is determined to raise the issue at the meeting on May 1 and wants the EFL to launch an investigation into the financial conduct of Championship rivals Derby County, Aston Villa and Sheffield Wednesday.
Exclusive: Bristol City set for busy summer of transfer trading whichever league they're in
According to the report, Gibson believes the three clubs are using loopholes to bypass the league new profit and sustainability rules and has been left "furious" that Boro sold £40m worth of players in the summer to balance the book but some of their Championship rivals didn't follow suit.
Gibson first raised his complaints at a similar meeting at Nottingham's City Ground in March and received support that day from Lansdown. Some league chairmen astonishingly even called for FFP regulations to be relaxed, outlining the split within the league's powerbrokers.
The growing relationship between Lansdown and Gibson was emphasised by the fact Bristol City sent a full complement of delegates to the Riverside for the Championship fixture on April 3 including the owner, CEO Mark Ashton and Chief of Media Lisa Knights.
Bristol City have consistently sought to cut their cloth in the Championship and, like Boro, made significant sales last summer with Joe Bryan, Bobby Reid and Aden Flint departing for a combined £26m.
The report claims that Derby are currently under a "soft transfer embargo" which has prevented them from signing Aberdeen captain Graeme Shinnie on a free transfer. The EFL have refused to comment on any aspect of the story.
Derby County insist they have been fully compliant with the English Football League's new profitability and sustainability rules and the club's accounts for 2017-18 showed a profit of £14.6m, largely due to selling Pride Park Stadium to a separate company owned by chairman Mel Morris and then leasing it back
Wednesday were placed under a transfer embargo between April and August 2018 and chairman Dejphon Chansiri, who put the club up for sale, said in January he fears another embargo unless the Owls can earn promotion.
"Unless we achieve promotion this season, we will again experience problems," said Chansiri. "I said it then and I say it now because I do not wish for bad surprises for our supporters. I wish to say it how it is and that way it is clear on both sides.
"To make our situation 100 per cent clear, we are not under any kind of embargo right now.
"However, if our problems cannot be solved by March when we submit our accounts to the EFL, another soft embargo is inevitable."
Birmingham City were docked nine points in March after breacihing the profit and sustainability rules. The Blues incurred adjusted losses of £48.7m, £9.7m in excess of the permitted losses.
