Well maybe, and this is what I think. Fat head wanted to curb the spending and save it for Kirkby. Kenwright (who has had doubts about Kirkby), wanted to give Moyes the money for transfers. Moyes threatened to not sign the contract until he was given assurances over the team, and not the long term future of the ground. Moyes has been known to side against Kirkby.
So a battle of wills ensued, and there is no way Kenwright was going to lose Moyes, so Wyness has clearly seen his arse, realised he's not going to get his way and make some cash out of Kirkby, and has jumped ship.
This is quickly followed by a statement from Moyes that he is going to sign his contract in the next two weeks, but he is working on getting in some new faces first. I don't believe AJ staying or going had anything to do with Moyes looking at bringing in Moutinho.
