Is it possible that Moshiri/Usmanov have thought of that before the invasion today ?
We all found out today the invasion is going ahead, I would guess the oligarchs have known this for some time and made preparations accordingly.
If this involves Everton only time will tell, but it isn't as if Usmanov is a direct owner of the club and if they then try to sanction businessmen from other nationalites who have business connections in Russia then the world economy , Europe and the US in particular, will collapse.
