Suspect they'll announce that the euros get cancelled and national competitions should use those freed-up weeks to complete.
Gives them time to delay a decision until later. And to look into managing the likely fallouts of that not being possible.
They've got 3 options: write off the season and get hammered possibly sued by those in table-top positions. Complete it later, but probably not possible in summer so more likely nearer the end of the year and shorten next season. Complete it now on current positions and likely get sued by those in table-bottom positions. I think the middle one is likely cos it gives clubs least reason to sue.
