UEFA and the European Clubs Association are pushing for a new version of the Champions League.
It would mean a minimum of 14 games for clubs in the group phase and 21 matches to win the competition.
The change would be apart of a three-tier structure to European football, planned to start from the 2024-25 season.
So far, the Prem clubs have resisted the proposals, telling ECA chiefs that they do not believe there is an appetite for more European games.
The Big Six are fearful that agreeing to the idea would have significant knock-on effects, both to the value of the Prems TV deals and forcing them to abandon the Carabao Cup, which would have a devastating impact on the EFL.
But Uefa and the ECA believe they have support from around Europe, not just the big countries, but the smaller ones.
