The fairest solution all round is to abandon this season. Start the next one when the worst of it is over in three months or so but make it a one off 23 team league, with no one relegated and the current top 3 in the Championship promoted. And also make a one off expanded edition of the CL, with the top 8 from the major leagues qualifying.
Proposed for the UEFA meeting,
the emergency one they are having after taking a long weekend, it will be rejected for all sorts of reasons but mostly legal ...
The only legal option open to leagues is to just right of 2019/20 and go back to the end of 2018/19 that treats all clubs exactly the same ... any 'fudge' that financially benefits clubs by granting unfair advantage, such as promoting or relegating a team who have played different fixtures, that's a legal minefield.
COVID is here for months this season is over and won't get finished ... whilst stopping all games should already have happened, there is no rush to make a decision on 2019/20 in the end the only logical decision is to just pretend the 2019/20 never happened ... scousers are going to melt
