It's not "115 charges" though. It's basically 5, but which cover a number of related rules over multiple years.
Charge 1 is about failure to provide accounts that give a true and fair view of the club's financial position relating to revenue and operating costs. This covers 50 combinations of rules/years.
Charge 2 covers failing to disclose player and manager remuneration. This covers 24 combinations of rules/years, 6 for manager remuneration and 18 for player remuneration.
Charge 3 covers failure to comply with UEFA's FFP. This covers 5 combinations of rules/years.
Charge 4 covers failure to comply with the PL's own Profit & Sustainability rules. This covers 6 combinations of rule/years.
Charge 5 covers non-cooperation. This covers 30 combinations of rules/years.
I guess it's possible that we could be found to have broken some rules under heading 1 in some years and not to have broken other rules in other years. But I doubt it. It's possible we could be found guilty of breaching the rules on player remuneration but not manager remuneration. But I very much doubt that we'll be found guilty of breaching some of the player remuneration in one or more years but not guilty in others.
Charge 1 looks very much like Charge 2 plus sponsorship agreements. I've said before that the PL will, in my view, struggle to land the sponsorship stuff, as did UEFA. Therefore in relation to financial offences it's mostly down to charge 2, I reckon.
If we're found not to have breached any of the rules in headings 1 or 2 in any of the years, then I'm 99% certain both 3 and 4 are both irrelevant, and the charges will fail by default.
The non-cooperation charges are probably the ones most likely to succeed, if any do. That doesn't mean I think they are likely to succeed but, like at CAS, are probably where we're in a comparatively weak position (although I think the issue of cooperation went to court, after which I assume we complied with any ruling).
While it's difficult to be confident without knowing the substance of the charges, I'd say it's unlikely we'll be found guilty of, say, 60 but not the other 55.
