I actually do feel sorry for him.
First and foremost he's a fan who's tried to do what we'd all try to do for Bradford if we were minted.
By walking away he's had to eat a decent amount of humble pie in recognising he's not all powerful and yes, moaning about the player seems silly but again as a fan he's probably not acknowledging they don't have the love for the club he clearly has. This is reflected in his theme of 'I gave so much why haven't you???'.
Simple answer Derek is they are not fans of the club, it's a pure business decision and that's where the likes of you and Green fell... from 'let's do it right' to gambling to become the saviour. The ego takes over and forgets you can't control everything...
I just hope Chalmers never becomes a Bulls fan
