I think despite all the naysayers i think this will eventually happen. Moshiri is putting in the groundwork to progress in all areas before Usmanov wants to be associated with us.
I would liken it to someone dumping their supermodel wife for a tramp that's 30 years older, at the moment it just ain't going to happen.
But if over a period of time we start to become part of the established top 4/6 and we begin to win trophies again, especially if Arsenal continue to stagnate, then I see it a matter of when and not if.
I don't think for one minute Usmanov is a life long Arsenal supporter, they just happened to have a great team at the time (based in London) and it just fitted in with image he wanted to outwardly display.
Men like him are not used to seeing anything bar marble, ebony and the finest leather, the common factor in all of these are that none can be found inside Goodison's more cattle market like innards.
However I'd imagine when his super yacht docks yards from his new super stadium and then walks into his own palatial suite decked out however he fancies, to watch one of the best teams in the world play, that will more than fit the image he tries to project to the world.*
(* this is completely my own personal view and I'm not affiliated to Moshiri, Usmanov or anyone else connected to Everton or Arsenal football clubs, or indeed to ANY other persons of notable interest full stop. I would therefore advise people to take financial advice before acting on the wild hunches listed above. I have been known to be wrong MANY times before.)
