we've got Rangers fans booing the Celtic players in the squad, Celtic fans refusing to cheer because the winning goal was scored by a Rangers playe

I think that's nonsense.

Although I have stood in front of guys at Hampden who have cheered every player bar Celtic players and vice versa which is all very petty.

Having said that, I remember being in Dortmund and Gavin Rae did something good and I said something along the lines of "well done Rae you dirty Dee bassa".

"The manager is a bit of a dud,the guy is completely out of his depth as Scotland manager and would be more suited as a pundit with BBC and wee Pat Nevin"

Who would you recommend instead?

"I remember Scotland v Norn Iron in the 1990s, when John Collins, still at Celtic at that point, was getting booed from both sets of fans."

Yeah that's definitely true - Scotland fans always boo Celtic players.

In your imaginary world, where everyone hates Celtic, including Celtic fans.
