Moshiri works for Usmanov
The vast majority of Moshiri’s wealth has come from Usmanov
Usmanov bought Moshiri’s shares to allow him to invest in Everton
If Usmanov decides he wants a controlling stake in Everton Moshiri will have problem with this
In fact I’d say that was the plan B all along , if the Arsenal thing did not work out , which it hasn’t
To add to this, Usmanov has never wanted to control a club from top to bottom. He didn't want that at Arsenal. He wanted to be able to have a representative at board level. Moshiri did much the same with Ryzanstev. If he has board representation (which he would have at Everton) he would be happy.
