I'm not going into the detail of the City charges but what I'll say with Everton is that their case was far more 'cut and dry' than the City charges as they were warned repeatedly about their FFP obligations by the PL but still went ahead and signed players and incurred losses, assuming they could write it off against Covid. The fact other teams complied with FFP and then got relegated means that they have a far more persuasive argument for compensation and, make no mistake, Everton will be sued successfully for many millions of pounds.
With you guys there are charges that have not yet been proven and that will take time and process. Plus these charges are all retrospective, there was no edict at the time the alleged offences were taking place where the PL said 'hey guys you shouldn't be doing this, please stop'.
With Everton the PL was warning them at the time they were incurring losses that they should not be signing any more players but they went ahead and did it anyway so it was far easier for the PL to find them guilty and issue the penalty.
