I have already explained the election of Nasser Al Khelaifi.
ECA can elect and nominate two people that will have a seat in the executive committee. UEFA merely ratifies the decision made by ECA. Before, it was Agnelli (Juve) and Gazidis (ex-Arsenal). When Gazidis left Arsenal for Milan AC, the rules states that the two seats can't be given to members from the same football association (here the Serie A). The consequence is Gazidis had to forfeit his position and a new election had to be done. Nasser, surprisingly, won that election. I'll not tell you how and why he won, i don't know, and i doubt anyone not in ECA know. The bottom line is he got elected by ECA members (the other clubs presidents and CEO) despite his vocal opponents like Tebas, the MU guy, etc. If i would hasard a guess, i would say that it involves the new Champions League format because PSG became vocal about ECA when there was that proposition (that i dislike) which will benefit the club greatly.
If you want to be cynical, you should note that tolmie said here that there is a guy from the Emirates in the CFCB chambers that is like secret services chief. Wouldn't a guy with such a prominent role in the UAE tip the balance in the CFCB dealings ? Why would UEFA be after City, then, since they have a guy inside the chambers that decide punishment ?
About the leaks, i have already shown they are quite frequent and usual. It can even be considered as usual practice for UEFA. The reason why ? Because it doesn't/didn't hurt them till now. UEFA considers itself as above everything as far as european football is concerned and as far as the old cartel is supporting them. Everyone is happy when there are news about PSG or City about to fail FFP : press, fans, other clubs. And it is an indirect sanction as it can hinder/lower some investment by potential sponsors. One thing that should be done first, imo, is to find a way to make all those fuckers like Tebas, Beckenbauer, Hoeness, Barca, Agnelli, Real shut the fuck up about other clubs matters. Why is it ok for Tebas and co. to pressure UEFA to do something about other competitors ? Even if we assume UEFA is neutral (they are not), it creates a climate where it becomes important or vital to sanction said clubs if one were to give a just ruling. When PSG escapes sanction, what is the sentiment, even here in a City fan club ? That FFP was not just and didn't sanction as it should. And the only explanation is PSG has bribed their way. No ones notice that by FFP regulation, when inflated deals are put in a fair market value, the club is not instantly punished. He is given the chance to balance his account if the 3 year period is not over. And this is exactly what PSG has done. So why are everyone so angry PSG didn't get punished when they have effectively breached no rule ! The UEFA statement is there is no wrongdoing !
In City case, it is not a matter of break even rule, it is about lying/misleading the monitoring inspectors. This is what Football Leaks said about your practices. In PSG Football Leaks, they only talked (as relevant facts for UEFA FFP) about the inflated sponsoring deals, which were already investigated by UEFA. Football Leaks didn't bring a new charge in PSG case.This is why i don't see why you want to compare two cases that have nothing to do with each other. The only similar trait is that UEFA wants you guilty and will use every method they can to achieve that goal.
