Last summer, the Premier League's transfer window opened on June 14 and closed on August 30, but the top-flight is ready to allow all 20 clubs to participate in FIFA's interim window to ensure no competitive advantage for Chelsea and City - a provision which is also set to be extended to the EFL.
Premier League clubs remain divided on whether to close the summer transfer window before the start of next season and restrict the January window to just two weeks going forward.
The world governing body has announced plans to open an interim transfer window - from June 1 - for clubs competing in the new Club World Cup, including Chelsea and Manchester City, to add to their squads before the tournament begins on June 14.
If clubs determine that the summer window should continue to run until the end of August, the Premier League may be forced to briefly close it midway through to comply with FIFA regulations.
The summer window has run until the end of August since 2019, while this January's window extended from the start of the year until February 3.
