It's well written and I take some of your points, but I can't agree with your main one.
I don't buy the Sun so I don't know what their overall coverage has been like of City. What I do know is they have a very good source. You'd be surprised. Trust me, really surprised.
The Sun is the most downmarket of tabloids. It prints what it's readers want: gossipy, bitchy stories usually spun from less contraversial facts. That's what it does. If people don't like that then they shouldn't buy it. I think our press is out of control, but that's a different argument. It is what it is at the moment.
City wanted to be at the top table. This sort of coverage comes with being at the top table. If we want to avoid our name being dragged through the mud then we have to be whiter than white. And Cook was a liability ultimately. A well meaning, square jawed, golf playing, cliche-spouting, belly laughing, man's man.
It was always going to end like this. The Guardian would have printed that story if they'd have got it, and Cook would have still gone.
Some City fans are shooting the messenger at the moment.
