Championship clubs could be set for a new "civil war" in a fresh row over transfers.
Sides, including Preston North End and West Bromwich Albion, believe clubs who have agreed wage deferrals with their players should be prevented from making signings when the transfer window reopens this summer.
That is according to a new report from The Telegraph on Monday afternoon, which claims that clubs that have not agreed wage deferrals believe rivals may gain an unfair advantage in the upcoming transfer market.
Both Preston and West Brom have not entered talks with their players over wage reductions due to the Covid-19 pandemic.
But Leeds, Brentford, Nottingham Forest, Bristol City, Millwall, Cardiff and Blackburn are all believed to have agreed wage deferrals with their players since football was indefinitely suspended.
Championship clubs are deferring player wages for up to three months to assist finances, with most agreeing temporary reductions of around 25 percent.
Preston boss Alex Neil has already argued that his side should not be outbid for players by a club that has had to restructure their wages.
Speaking to Lancs Live, Neil said: "If people are taking wage cuts or deferrals then people are putting cases forward that they shouldn't be allowed to sign any other players.
"Because if they can't currently pay the players they have got then why should they then be allowed to use the money they have deferred from wages to then invest in their squad to bring better or more players in?
"I don't think that clubs who have run their finances in an organised and good manner should then be hampered and hamstrung when other teams are maybe slashing wages and then the window opens and we get out-bid for a player that they have brought with money that they have deferred from another player.
"That cannot be fair. So it will be really interesting to see how that comes out in the wash."
While in the same report, it is claimed that EFL chairman Rick Parry will attend a select committee meeting on Tuesday.
Parry is likely to be questioned by government ministers on the impact the coronavirus crisis has had on the EFL and its clubs.
Both the Rugby Football Union and English Cricket Board are also expected to be present at the meeting.
