Based on the North Korea state of the lack of information from the club recently, for Moshiri to break cover like that seems odd to me.
But like you say, no denials. Yet. Maybe they dont know!!
For info...
It was Jim White presenting SSN when BK text apparently issued the statement on Stones going know where, via a text and then later on via the website last season.
It was also Jim White presenting at the time when Sky got the statement from Moshiri a week or two ago saying were delighted re Bolasie and pushing on.
My hunch is that this is someone at Everton who has a relationship with White, probably B Doogan and placing names next to it, i.e. BK/Moshiri.
Whether they need approval is another thing but nevertheless, its terribly naive on all accounts.
