It amazes me why people don't seem to understand the reason behind Man Utd fans, shall we say, dislike of the English football team...

Here's a few reasons...

England fans booing Utd players when performing for England...
England fans chanting that they hate Man Utd...
England fans abuse towards Becks back in the day...
England fans abuse towards Sir Alex...
England fans conduct and behavior when in other countries...
England fans conduct and behavior when in this country...

Need i go on?
