Totally disagree with the mentality 'manager asks, CEO fulfills his wishes'. Maybe after the manager proves himself, but not by default.
A lot of people seem to think that Mourinho is Ed's boss, when in truth it is the other way around. Mourinho has to justify his decisions to Ed, not Ed to Mourinho. Same as in any other type of work. As much as I would like to, I cannot order my boss to buy a DGX and then if he doesn't do it, to say that it is his fault for the project failing.
Well if any manager in world football has proven themselves its Mourinho. When you win the CL with Porto and a treble in Italy then you have earned the right to ask football neophyte investment banker Ed Woodward for the players you think you need to advance the club's objectives.
