One Liverpool fan took the Liverpool and United rivalry that step too far when he had his backside tattooed.
The 'fan' is question has subsequently deleted both his Twitter (where it was initially published) and Facebook page following the inevitable flurry of abuse.
The tweet which can no longer be viewed, read: "Think my hatred got the better of me last night" and was accompanied with the photo. The tattoo says 'Munich 58' which of course is directed at the Munich air disaster in which eight Man United players lost their lives.
Puts a whole new meaning into the word a**e-hole.
