I found a useful summary of City's charges:
Failure to provide accurate and up to date financial information - 54 charges covering 2009 - 2018.
Failure to provide accurate financial reports for player and manager remuneration - 14 charges covering 2009 - 2018.
Failure to comply with UEFA licensing and FFP regs - 5 charges, period unclear
Breaches of PL PSR rules - 7 charges covering 2015 - 2018.
Failure to cooperate with PL investigations - 35 charges covering 2018 to the date the charges were made.
I think I've said before that I believe the PL will have charged them with anything they might be guilty of. There's a good chance a lot of the charges will not be proven (no doubt leading Pep to say they've been "exonerated" again), but the reason for this will be more likely that the PL don't currently have the information to know whether the charges are valid or not so they've thrown as much shit at the wall as they can, believing some of it will stick.
And I think that when this case is done, further charges will follow for 2018 to date.
The PSR charges cover a shorter period. This may be because the rules weren't introduced until 2013. I'm not sure when the first reporting period was, but it could conceivably have been 2015-16 (covering 2013-2016). The others run from 2009, the first full season after the ADUG takeover.
The failure to cooperate will, I think, be a real issue for them. It's clear they didn't, and there's been a lot of focus on this in the Everton and Forest cases (and likely in the Leicester one too). The Leicester case is likely to give us an early indication on how the commission will react to the failure to cooperate as Leicester are going down the same route as City - claiming innocence and therefore no requirement to cooperate. I don't see that ending well.
Feel free to unload your "nothing will happen" comments below, but I'm choosing to believe the glass is half full.
