Fair. I think the problem here is that there is an implication from these people who suggest Ed does not get the final say. The implication is that Ed is making all decisions, often against the desires of those involved in making decisions. I would disagree.
My understanding of how a football club with a DoF works is as follows...
- DoF/Manager/CEO discuss goals and transfer budgets for the season.
- Owners/Board/CEO decide transfer budget for the season. This is likely the only time the owners are heavily involved.
- Chief Scout/Manager/DoF identify targets over time based on budget.
- DoF works on these targets. Speaks with agents, clubs, players, etc. Through this research, he establishes what he sees as the right price for the right player.
- Board/CEO/DoF/Manager meet to discuss this 'right player at the right price' when the price and wages required become apparent. He explains his justification.
- Board/CEO/DoF/Manager discuss and decide - as a group - what they believe the best course of action is.
- CEO signs off the funds, usually with a very quick call to the owners. So long as it is within the budget, the owners will agree immediately. If it is outside the budget, CEO would have to justify the commercial value of this request (eg. will it pay off eventually for the club financially). This is the part where the CEO is , effectively, in control and can "override" the DoF. However, any club with a decent management system will not have a CEO that will suddenly turn on the board, because the board more often than not appoints the CEO.
Could have some details wrong but that's generally how I imagine it would play out. I've been a boss of a group before with the ability to override people. You don't do it, though, unless you have extremely good justification. You are involved in the discussions, you can disagree, but if everyone else on the board is at odds with you then you tend to accept this. Ed won't be going "I know better about football than you." He will however be considering "I know more about finances than you." So the only real instance I can see Ed saying "no" is if it is a case of a financial decision rather than a footballing one.
A great example for me is that of the Mourinho escapade recently. Fred was signed very early on, and Mourinho suggested that he could not play Fred without a more reliable center-back. Mourinho may have spent all his money on Fred and then found that the center-backs he was after costed more than the remainder of the budget allowed. In this case, Mourinho should have planned better. If he wanted to buy a center-back but spent all his money on Fred, who he could not buy without a center-back, he should have looked into this considerably earlier into the planning. They should have waited on Fred and got the center-back first, and then looked for Fred at that point. If he had to get both and did not have the budget to get both, then quite frankly you suck it up and get either one of them or neither of them.
And, it must be said, we had five center-backs at the club, two of which Mourinho bought himself, so Mourinho didn't have much room to argue back if the budget wasn't there.
If the board felt the cost being quoted was too high - and I wouldn't be surprised if SAF/SBC both scoffed at the idea of paying £70m for a center-back unless he was unquestionably world class - then the board would have rejected it before the CEO could even get to the option of signing it off.
