Might not help us, they screwed up big time..
UEFA closed the FFP compliance investigation into PSG on 13th June 2018, finding no fault. On 22nd June, they decided to re-open the case, but only formally did so on 3rd October, which violates UEFA's own rules that required them to re-open 10 days after announcing they would.
In other words, UEFA failed to follow their own articles of procedure correctly, with Article 16 (1) being the key clause of the UEFA Adjudicatory Chamber convention that they did not abide by. Massive legal own goal from UEFA.
The outcome is that PSG are not in danger of receiving any FFP related punishment until the latest round of checks, which will occur for all clubs at this season's end.
