THe manager picks the man. The Execs hash out the cash. The the execs go to the manager after and say:"This is what we've managed to get out of this Mr Manager, £XXm with wages of £XXXXXX. Do you want him?"
At that point of the situation, the manager comes in and says Yes or No. That is just how it works. I live in London. I do journalism. I've met with many senior football journalists who concur with the process.
Now, is Moyes to blame for accepting the £27m offer the Execs managed to hash out with Everton? I would say, yes. But, David Moyes is not a stupid man. This is a man who built an extensive scouting system at Everton and made some very good deals over the years. Suddenly, he goes tits up and doesn't know how to do transfers? No, I don't believe for one second that that's what happened. There was a massive top-down change at Old Trafford and everyone was new to the job. Ed Woodward was the finance man and he didn't know anything about transfer deals. Everton took the mickey out of him and everyone who comments on football knows it. Note that almost every single pundit, the sensible ones I mean, say that Manchester United had a bad transfer window. Not Moyes, Manchester United. It was a group screw up. But, the guys who hashed out the deal gave Moyes two very poor options - Sign no player or Sign someone he knows has skill and ability, and has shown glimpses of real quality. Granted £27m was way over the top.
This is why you saw Moyes running around in January. He took matters into his own hands in trying to set up deals. He realises that a lot of groundwork needed to be done before the summer so that deals could be done quickly and efficiently. Let us look at the summer and see just how well he does.
If he really was so callous about Fellaini, then theoretically he will spend a lot of money poorly this summer. Why does the United board trust him with the cash? Why are they willing to let him spend? Because they know it wasn't his fault entirely, as to what went wrong in the summer.
