It all stems back to the same problem, lack of leadership from the outset. First thing you do, audit the board, bring in your own chairman and CEO with relevant experience of running a successful elite sporting organisation. Second thing you do, make sure that they put a clear structure in place. Third thing you do, let them remove the manager and employ a manager with at least 5 years experience of successful club management in the top division of a major football league, and preferably with experience of turning a sleeping giant around, or turning a habitual mid-table club into a trophy winner or regular European qualifier. After you've done all of that, you give them a good budget to work with and allow them to get on with their job.
None of this happened, and therefore Moshiri needs to sell the club to someone with the common sense to do this.
As for a split, he fell for Kenwright's bs so I very much doubt that they are best mates now.
