Let’s remember this is about more than the PL winners there’s lots more to consider
European places
Relegation
Promotion
Cup competitions
It involves the whole of the football pyramid
Lots remains undecided, so there is no way that the season can be declared as competed until all matches at all levels have been decided. Therefore the decision should be made at UEFA level, initially to cancel all cup competitions and to suspend leagues for4 weeks pending upon a review, with the option then, to void the season or continue in some form
I don’t see the season being valid until everything is magically certain regardless of how many points a club is ahead Any criteria would have to be applied across the whole of football
