You're talking through your arse(nal) here. This is absolute nonsense.
First, the 5-year limitation period is in UEFA's FFP rules, and nothing to do with CAS.
Second, we were cleared by CAS of the substantive charge levelled against us by UEFA's CFCB, which is that our commercial sponsorships were disguised equity funding. The initial press release from CAS, on 13th July was quite explicit on that point.
Third, the time-barred element of the case (the Etisalat sponsorship) was examined by CAS, who cleared it as being done properly. This oft-repeated claim by the hard-of-thinking, that we only got off due to time-barring, is a complete myth.
Finally, although it's not stated explicitly that there's a time limitation in the PL rules, it is stated that English law applies, which means there's a 6-year limitation period. They can go back further if there's evidence of criminality or fraud though, which is effectively what we've been accused of. But if the PL's Independent Commission finds no evidence of fraudulent activity then pretty well every part of the PL's case falls as time-barred. And if there's no evidence of fraud, then it's highly unlikely we did much wrong at all anyway, which is a double whammy to our detractors, like you.
They say 3-word alliteration is a powerful communication trick so I'm going to use that technique and call you a thick Tarquin twat.
