I was in a box on Saturday and I will give you a first hand impression of how it gets out of hand and mishandled.
Yes there were three Burnley fans in our box, two of them behaved well, one, a gent of around 60 did jump up and wave his hands about to celebrate. He was an old man that had been supporting them through thick and thin for 40 years, He was made up with the way his team was playing that is all. We told him if they scored again however to go into the box out of sight as it could be taken the wrong way. Purely and simply the occasion got the better of him and he was just excited, nothing more.
This as well as a few other Burnley fans standing when a goal went in meant that he was singled out for an absolute onslaught of abuse.
In a box further down, a life long city fan and the father of one of the clubs senior staff was called every name under the son (you fat **** etc for about 50 minutes of the game because he was singled out as a Burnley fan. He tried to explain and was given even more abuse. When City went in front they then appologised? so it seems they knew he was a blue anyway but wanted to take out the result on someone, Please tell what is that really all about?
