I think the only two realistic options are either find a way to complete the season or declare it null and void, otherwise it's going to be massively unfair to decide relegation and European spots based on the current table. Liverpool being named champions isn't an issue because they could put out a reserve team with only 9 men for the rest of their fixtures and easily win the league. But there are clubs, including us, who have had a more difficult fixture list than others so far, the only fair way to decide it is by doing it when everyone has played the same fixtures, that can only happen after 38 games, otherwise it should be declared void.
