The Guardian has a clear editorial stance with regard to City and is rigorous in shoehorning it into every piece on us, no matter how tangential or irrelevant. To that end, the notion that City are "sportswashing" is presented as unimpeachable fact.
In truth, it's contentious at best, promulgated by purported experts with a manifest self-interest in doing so. And no one has yet evinced a persuasive theory as to why the UAE should feel itself constrained to pursue such a strategy to win the hearts and minds of the public when it already manages to construct lucrative, cordial relationships with all types of countries across the globe.
TL,DR - see the message I quoted from
