You'll probably find that it will come out later on (if it is true) that it was nothing to do with football and because it was on old firm day it has been made out to be. There's stabbings every single day in Glasgow.
Aye i'm not going to say i know the crack of whats gone on etc.., just some mates and others have been on about it just know theres a few scottish folk on here so wondered if they could confirm this or if it is just a sick rumour.
I expect the violence to get worse, with the financial situations of both clubs getting more and more dire, hostilities amongst rival supporters is only going to increase due to venting frustration.
