This would the first domino to fall. I sense this would be Liverpool's argument too. Just hand us the title and forget about everything else. The exact sort of scab mentality we have come to expect from that club.
Unfortunately for them it won't work like that. Believe me, the moment the PL make any kind of declaration based upon this season Pandoras box is opened. Leeds and West Brom are going to say they should be allowed to come up. Fulham will say the same as the third place team. Teams 3-6 will say they planned to finish strong, catch them and should therefore be promoted. Probably 10 sides in the championship will say they deserve the right to compete in the play offs. They would all have strong cases.
Worst case scenario you have to promote 2 teams and have a lengthened season in what will be a tighter time frame.
In the PL sides are going to get into a massive bunfight about who deserves European football. Expect Leicester and Spurs to both pipe up in different directions. I would even expect us to make a case, that given our post Silva form, and how close to we are to European places we should also be launching a civil action.
Thats just me, off the top of my head. I'm sure legal advisors for other clubs will be thinking well beyond that and politely letting the PL know. I mean the inference I get from Brady, is that she will let the PL know she is not expecting any relegation this season. However it's hard to see how you can't have relegation and declare the league invalid on one hand, but on the other state you can have valid champions. It doesn't work that way.
