I've convinced myself there's a good reason for that.....what I can't understand is why would Usmanov come in now and not when Moshiri first invested. Surely if they wanted to buy EFC as a partnership they would have done it from the outset.
If the plan was always for them both to move to Everton, it makes sense that the quickest way to do that would be for one to sell their Arsenal holding to the other.
That Moshiri sold his Arsenal shares and then immediately bought the Everton ones suggests there was reason to hurry. Presumably the reason was the Americans.
Perhaps if they'd had more time, it would have been done differently.
