No offence but what is the relevance of this? I'm sure there are some people that don't understand the reference but somebody that prints it on the back of a football shirt clearly does. He hasn't done it by accident nor for any other reason. He clearly knew what it meant, hence why he done it.Playing devil's advocate, an 18 year old and/or foreigner might not know what it means.
Despite being 39, i only learnt of it in my twenties when i moved to the uk aged 15, despite being a lifelong utd fan.
Anyway it's been reported that he's now been charged. Whether the charge amounts to anything remains to be seen but this ****head being outed as a scumbag, getting himself arrested and who knows what else will come his way, will hopefully deter other morons from doing similar things.
