I suspect that any relegation would be as a result of a points deduction, not an additional relegation. The EFL and PL are different entities so they can't mandate an extra relegation into the league below. If they're relegated, it would be part of the traditional 3 slots and on -50 points. It's why the likely relegation could only be as far as the Championship and no lower, unless the EFL also apply an additional points deductionGenuine question, IF Man City were demoted to the Championship as punishment, would one less team be relegated from the Prem or would one extra team be promoted from the Championship to keep the PL with 20 clubs?
