Exactly what the cartel behind it intended for it to do: cast doubt on the legitimacy/legality of our undertakings and successes, and degrade our reputation (brand, in the wider context).
It was never meant to be a serious investigation, as they know they do not have sufficient standing or evidence to make claims that would withstand scrutiny outside of an “industry regulating itself” regulatory environment. They could try to do what UEFA did — ignore evidence and repeatedly impose sanctions for the same supposed rules violations — but we would most certainly take any such actions straight to court. That itself would likely eventually put the PL’s own FFP (among other regulations) at extreme jeopardy; neither the PL nor UEFA (even Ceferin who does seem to want to reform both the organisation and FFP) want that to happen as it could delegitimise the organisation’s themselves (as even this latest CAS verdict has with UEFA to a lesser degree), leading to all sorts of collateral consequences.
These PL and UEFA investigations were meant to last for a long period of time, provide many opportunities for friendly persons in media to write about them, keep the distrust and vitriol toward City at the relative forefront of the mind of the football community at-large, and do as much damage to reputation as possible in an attempt to bring us “back down to our station”.
Some of the PL “charges” now being referenced by the media in the aftermath of the CAS decision aren’t even actively being pursued anymore by many accounts, but the PL has not come out yet to clarify what is still being reviewed. And there is a reason for that.
It is a farce, by design.
