To be honest, this shows the two main problems with football fans nowadays.
1- No respect for other fans or other clubs even if it is your main rival. The Man City fan didn't deserve to be murdered though (no-one does).
2- Over reacting. Yes what the Man City fan said and did was disgraceful but to get a knife and kill the person with intent is an over reaction.
It's such a shame that people that take everything a bit too seriously or don't show the slightest bit of respect ruin the beautiful game. |
