I could well be wrong but people seem to have this notion that everyone at City would know what the outcome was if it had been reached. And if it was informally communicated in April, then it'll still be the same outcome in August. The delay isn't going to change that.
But it's been said before that both my source and Stefan & Ahsan's source could be telling the truth. The knowledge could be restricted to a handful of individuals on both sides, who have agreed to non-disclosure. I'd postulate that, if I'm right, the knowledge is limited to board members only and maybe only Khaldoon & Simon Cliff at City. Maybe John Macbeth as well. The Chief Marketing and Finance Officers, who are not main board members, may not know.
If we go back to 2008, there was no leak prior to the day of the announcement of the sale to ADUG. That's because they'd insisted on strict NDAs, documents that the Everton board wouldn't sign but we did, which led to ADUG withdrawing from negotiations with Kenwright.
While City may not be too keen on the PL leadership currently, I can't imagine they want the complete chaos that might ensue from a bombshell announcement and (as one journalist speculated) civil war if the PL, or some of its members, are shown to have acted in bad faith.
