I personally, would never used a derogatory term to describe Football Clubs, their players or fans.
I can say that Liverpool did not play well on Sunday and M.U. deserved to win as they were the better team on the day. That is a fact. However, the one player from Liverpool Wayne Rooney, was a big disappointment to M.U. for missing the penalty, but I know a lot of Liverpool supporters enjoyed that.
I would aver that Wayne Rooney didn't miss the penalty, he hit the ball very well, the ball was on target, the Liverpool goalkeeper saved it , a good save, and not a miss by Wayne Rooney, there is a difference !! ;-)
