At the risk of pushing the point, UEFA wouldn't have seen who paid the Etisalat invoices from the audited annual accounts. They would have needed access to the underlying accounting records and I am pretty sure they didn't in 2014.
Anyway, this has gone on long enough. We both agree the PL won't be able to prove their allegations to the extent required, I think.
Why wouldn't UEFA have had access to the related info they needed?
1. City & Etisalat agree a sponsorship deal.
2. Etisalat are entered into our ledgers as a client account, & an invoice is raised.
3. City receive payment for the invoice which is credited to Etisalat's account.
4. UEFA ask for bank statements covering these transactions.
5. It's found the Etisalat invoice was paid by UAE Financier, Jaber Mohammed.
6. Questions asked: Why would Mohammed pay Etisalat's invoice?
7. Etisalat used Mohammed's services to secure a bridging loan to pay City.
8. Etisalat repay the loan to Jaber Mohammed in 2015.
9. UEFA note this point, but it really becomes relevant with the Der Spiegel article citing one line of a stolen email where words to the effect of "Perhaps we can get His Highness to cover this payment".
10. Discussions ensue to identify who is the unamed HH in the email.
11. To prove their points, UEFA need the financials & bank statements of Etisalat, Jaber Mohammed, & ADUG to prove their claim that ADUG paid Mohammed, who then paid City.
12. Both ADUG & Jaber Mohammed are outside of UEFA's jurisdiction, so UEFA had zero evidence to provide CAS outside of "On the balance of probabilty" that the HH mentioned in the stolen emails was Sheikh Mansour, & through ADUG, he funnelled equity funding to Jaber Mohammed, who then funnelled the money to Manchester City, disguised as Etisalat Sponsorship.
UEFA seeing the bank statements relating to accounting transactions, would be standard I'd imagine, because it is when HMRC are having a look at your books.
