I think part of the difficulties that are playing out, in the wider football world, in typical EFC fashion is we are not communicating our true intent particularly effectively to the outside world. Moshiri seems to make the occasional outlandish remark but then back it up very little with any kind of reform within the internal aspects of the club. He then seems to run a parallel search for a manager, and much of the detail he gives seems very private so it doesn't really change much consciousness of the club in the wider public and media.
I think that leaves other chairman a bit bewildered and then concerned as to how to justify this to their fan base. From our side it makes me wonder exactly why he is operating in this way. For an astute businessman it's clear it's far from ideal.
As for Silva, I sense he will be here 18 months. It may only be 6. Both Silva and Everton (or at least the Moshiri faction) seem to want to move their own trajectory upwards very quickly. Unless this happens for both parties at the same pace it's difficult to see that lasting beyond a medium term arrangement. I don't think it's what Everton ideally need currently, but sometimes you have to compromise before you can get to the position you ideally want to be. Koeman moved us forward, before dropping us back to square one, and I think Silva will do the same. That should allow the club to potentially reach a higher calibre of manager (ideally the long term one) next time with hopefully a handy compensation package when Silva moves on.
