The real difference about PSG case is that they pursue PSG over the inflated deals. PSG had to go to CAS to win on a technicality. And even then, PSG had to sell for 145 M€ of players to comply. It is not a sanction in name but it is effectively a sanction.Nothing is going to happen. The last wo paragraphs say it all. If PSG get away with no fines and bans so will we.
They attack City over another angle, which is the truthful reporting of financial affairs. PSG has no problem in that sense (so far) because they were pretty transparent and straightforward with those big inflated sponsorships like QTA.
Also, the Nasser tidbit : they should remind how and by whom he got elected. It is not UEFA electing him but ECA members (the CEO of the european clubs). He wouldn't have got the position if Gazidis had not left for Milan AC and i suspect that the overt support of PSG on the new Champions League helped.
