If I had just spent several £100 million on a club who have finished mid-table last time out and will finish there again this season, particularly one with an out dated stadium I'm not sure I would feel the need to explain myself to the fan base in the first month. I would think they should have the good grace to accept that when I say I will provide money for transfers and look at the stadium then that is what I will do.
I definitely wouldn't feel the need to lay out my plans in detail, it is not as if I would be looking to run the club by mutual consent.
Moshiri owns half the club, he has made a statement of intent, it is more than we are used to.
