In fairness people who go around on nights out just to smack people are absolute scum.
I blame the lasses who hang around these idiots. They cause the trouble shaking their arses around then are nowhere to be seen when these jealous scum attack someone.
Don't know the full story but I wouldn't be suprised if that's what's happened. Girl see's football star, girl goes over and let's him chat her up, jealous lover comes over and chins him for getting too close.
