Yes; those payments have definitely been made for 75%, yes it has been widely reported (the athletic primarily, who undoubtedly would like to see the league continue) that the PL will have to pay the full amount back. Who knows where the actual would end up, but if both are true and the league is voided no doubt there would be a lot of legal teams making a lot of cash...
I'm assuming Gary Neville's neatly timed tweet saying the league must be completed reflects the views of his employers and that remains their stance on it, this will undoubtedly calm over time as this season fades in the memories.
Gary Neville has changed tack and is speaking on behalf of Sky.
I'm not saying it's impossible they choose such a law suit, or even that they might win. However all I would add is
1) Such an act, to take back money already provided to the league would destroy the league
2) If Sky were to pursue this, it would kill the relationship. It would never recover, it would be an act of war from Sky.
3) If thats their thinking, that ostensibly they either want to bail, or they cannot afford it anymore then they will use any excuse to withdraw money. A season finishing late, games being clumped together, or at unusual times, and especially games being shown on different platforms (if behind closed doors) would also necessitate a likely legal challenge.
The Athletic are in Liverpool's pocket and sky's currently. However I do not see much sense of Sky pursuing an avenue of wanting all money's back. It would be an act of war. I suspect they will want 1/4 back.
I mean it's a hard argument, as 3 weeks ago I was saying cancelling and just installing a champion wouldn't be enough to safeguard the TV money's, which people felt ridiculous. It now seems to be going the other way.
I think Sky still have an interest in football. I think they will want 1/4 back out of court to avoid legal fees. They will demand a full season next year though. We can afford to lose 1/4 of fees. We cannot afford to lose 1/2 or even a whole season next year just to save 1/4 this year.
