Most teams have 9 matches left?
Although far from ideal, I guess this could just about be squeezed into a 3-4 week window if Euro 2020 is cancelled.
Those logistics aren't too bad. You might even truncate it if some matches become irrelevant for anythign meaningful beyond actual finishing position (e.g. Saints v Sheff Utd might well be a dead rubber, in which case don't play it).
Problem could well be the logisitics in arranging this, not the will. If UK is basically locked down for a couple of months, how bad is the deterioation of pitches, how unfit are the players, how fast can they gear up ticketing, stadium safety etc?
The June 30th contracts ending for some players is also a legal minefield - might teams with somethign to play for sign a ringer just for a month etc?
