If we are to take K9's post as being right (and we have no reason not to so far) I note you are choosing to ignore the involvement of Paton (born Greenock) and Duff + Considine (both born Aberdeen).
Anyway, I can't be arsed getting particularly indignant about this.
We all know there seems to be something of a drink culture at the club. We also are aware that the first team squad and management have a collective IQ akin to that of a postbox. Furthermore, their disdain for the Aberdeen support has been well documented through both performances and behaviour over the last few years.
So, am I surprised? No.
Particularly concerned? No. Simply because, I can't see this culture changing while the current manager remains in charge.
