This is from Der Spiegel:
"That money is then "routed through the partners and they then forward onto us," wrote Finance Director Andrew Widdowson in an email. That, at least, is how things were done in 2015: At the time, the deal with Etihad was bringing in 67.5 million pounds annually. But Chief Financial Officer Chumillas emphasized in an email to Pearce: "Please note that out of those 67.5m pounds, 8m pounds should be funded directly by Etihad and 59.5 by ADUG."
This from Reuters:
In an August 2013 email, Jorge Chumillas, then chief financial officer at City Football Group, the company through which Sheikh Mansour controls Manchester City Football
Club (MCFC), asked Pearce about the arrangement by which money flowed through Etihad, an airline owned by the Abu Dhabi government
"I need to understand the mechanism by which additional sponsorship flows through ADUG.
Is it ADUG Shareholder->ADUG->Etihad->MCFC?
Or is it rather ADUG Shareholder->Etihad->MCFC?," Chunillas wrote.
Thanks. There's more substance to it than I remembered, but it's still highly selective quoting that can't be taken to be remotely conclusive in the absence of other related correspondence and thus could be completely misleading.
