My belief is this is pretty well about Fordham and Mancini's Al Jazira contract. The latter is immaterial and at the very worst, even assuming it's not time-barred, might result in a fine if the independent commission feel it's out of order.
Fordham is more difficult to call. They were originally Manchester City Football Club (Image Rights) and a club subsidiary. The were incorporated in May 2012 and appear to have stopped trading in 2018. They're currently being liquidated. Our wage vill shot up in 2019, from £260m to £315m, which while not absolutely conclusive, suggests that we started paying image rights via Manchester City Football Club then. Or it could be related to bringing one of the other subsidiaries (Manchester City Football Services) back into the main accounts.
Whatever the legalities of Fordham, we must have taken expert advice and there was a clear trail from Manchester City Football Club (Image Rights) to Fordham Sports Image Rights. Our auditors must have been aware of this and presumably would have asked the relevant questions. Assuming they did, had they not been happy they'd have walked away and/or qualified the accounts. They didn't so we must presume they were happy with the answers given.
Also, the Fordham situation was revealed by Der Spiegel iirc, or was publicised somewhere else, so it's hardly been a secret.
