And my guess would be that they're claiming we've overstated sponsorship income, and that we should only have recorded the £8m Etihad provided rather than the £50+m that Etihad were given from central Abu Dhabi funds.
I assume they're saying that latter figure should have been recorded as equity, which is utterly bizarre. As long as the additional money didn't come from ADUG then it's none of their business. The evidence presented at CAS proved pretty comprehensively that the funds didn't come from ADUG.
