i think regarding the usmanov thing.
It is very possible he could follow, if you judge on their past business ventures it is very rare where one goes, the other does not follow.
That is not to say Moshiri might have not fancied breaking away from the mould, and attempting to forge his own career but at a club that will require a lot of investment and work on i do believe it is unlikely usmanov will not be involved at some point.
Both of them as a joint alliance have been attempting to purchase arsenal outright for years, it is very plausible to assume they have given up and decided to do what they had planned with a new club, i.e us.
It has been years of trying to do something with arsenal and it just hasn't come off because of their other owners, here it will be much easier for them BOTH to implement things they would like and everton really do have a lot of things going for us, we could become a very good business venture and project.
Like i said it is not certain that Usmanov will join his friend, but judging by the past it is very likely that it could happen, and it just gives Usmanov time to sell his shares to the best bidder at Arsenal, Whilst still having insight into everton with Moshiri running things until Usmanov can come on board.
All guess work, though but i wouldn't be surprised, at all.
