One flair landed near me. It is incredibly stupid to do something like that.
On another note, United have to worst fans I have ever come across. No original songs, just re-hashes of whatever we were singing for example, "we won it three times, without killing anyone....".
My personal favourite was "Steve Gerrard Gerrard, he kisses the badge on his chest, and hands in a transfer request"
A minute later Rooney comes across to take a corner and the same fans "ROOOOOOOOONEEEEEEHHHHHHH"
Embarrassing really.
