If people think violence at football is rare and the mancs and spuds are c*nts they are deluded. I have been to enough matches and a few euro aways in my time to know its not rare.
Granted its pretty rare to see full scale brawls in stadia but you ALWAYS get the odd fight in and around the ground. Football is watched by mostly men who like a good drink, you only have to go into town to see what a couple of bevvies does to people.
