I'd like to see the legal justification that would have to be released for Liverpool to be awarded the league title without actually mathematically winning it. Even being extremely charitable to them, it's not like they're just one win away from securing the title.
Some sports have actual rules that cover such eventualities - i.e. - if a F1 GP doesn't got the full distance, the leading driver is still awarded full points and the win if 75% of the race's completed. No such rule exists in the Premier League. Therefore there is no legal justification to award Liverpool the league.
And why would the team in first place be awarded the title, but the 3 relegation zone dwellers not relegated? It has to be consistent across the board otherwise it is totally unfair. It would also have a knock-on effect to the rest of the professional football league system. Would Leeds be automatically crowded Champions of the EFL Championship - and if they were, how would they be promoted if no one from the PL is relegated?
