I like your confidence, but if this loophole was allowed, then anyone could surely buy a club, so long as they used a more complex company structure. Doesn't feel like it would hold up, unless the rules were particularly badly written, and couldn't be changed.City is a wholly owned subsidiary of CFG. Mansour owns more than 75% of CFG so he is listed in City’s accounts as a person of influence. But he has no ownership rights such as buying and selling shares in City.
How about explaining how he's also not a member of the UAE Government? I know some argued that when he was a vice president, it was more a ceremonial title, but his role as Deputy Prime Minister is clearly Governmental.
