Manchester United, Manchester City, Chelsea and Wolves are expected to be given extra time off by the Premier League and start next season late, should they go into the latter stages of their respective European competitions.
The Premier League is likely to ring-fence a guaranteed 30 days off for players to recover, from the day after their final European game of this season.
The matter will be discussed, and could be ratified, at the next Premier League AGM, which is scheduled for August 6.
If the proposals go through as planned, should Manchester City or Chelsea make the Champions League final on Sunday August 23, their first Premier League game would not be until Tuesday September 22 - 10 days after the official start of the new season.
For Manchester United and Wolves, if they qualify for the Europa League final on Friday August 21, their first Premier League game of the new season could not take place before Sunday September 20.
The new Premier League season will start on Saturday September 12, but English teams involved in the latter stages of European competition would see their opening fixtures postponed and played in midweek to catch up.
Champions League key dates
|August 7/8||Four remaining last-16 second legs|
|August 23||Champions League final|
Europa League key dates
|August 5/6||Round of 16 remaining ties|
|August 21||Europa League final|
A further complicating factor is the round of international matches, scheduled to take place before the new Premier League season starts.
England manager Gareth Southgate is likely to begin his training camp on August 31 - five days before the first Nations League match against Iceland.
That could mean Manchester City's England players, including Raheem Sterling, John Stones, Phil Foden and Kyle Walker, only getting a week's rest after the Champions League final, before they were called up by their country.
Southgate has always taken a pragmatic approach to these issues, and in such circumstances would be likely to have a staged call up for players who have had different workloads.
Additionally, Chelsea's potential involvement in the Community Shield - date still to be decided - could be an issue in the unlikely event they can overturn their 3-0 first-leg defeat to Bayern Munich in the Champions League round of 16.
It is all part of a testing schedule for the clubs, and a logistical nightmare for the Premier League itself, in the aftermath of the coronavirus lockdown.
Football calendar - all the new dates
Football is back and a new calendar is taking shape. Champions League, Euros and more - keep track here.
While a number of top managers voiced their concerns about the hectic schedule since football's restart, there's also been high praise for the Premier League - and its strict protocols at training grounds and stadiums - and its rigorous testing procedures, allowed for the remaining fixtures of this season to be completed.
For next season, league officials are likely to have just two weeks from the Championship play-off final, to prepare for the announcement of the fixtures for the new season.
The summer transfer window will run for 10 weeks from July 27 and close at 11pm on October 5. A domestic-only window for trades between the Premier League and EFL then runs from October 5 and closes on Friday October 16 at 5pm.
