Just to clarify, this is from an extremely reliable source. ..the Everton fans on the coach were being taunted by Watford fans who were 'kids', when the Everton fans were wound up the leapt off the coach and the kids ran off. The Everton fans (who have been done for class A drug possession) jumped the graveyard where a man and his son who live in the house there were just reaching home from the game. The 4 Everton fans, plus about 8 others, attacked these 2 unsuspecting Watford fans, one of which now has a brain bleed, a damaged eye socket and a fractured skull. His son suffered cuts and bruises. There was also a scuffle in town but I haven't heard much about it, except that there was fighting. This did kind of knock the shine off a darn good day!
This corroborates the account I have heard through friends of one of the injured. Quite different to some of the fabricated stories on Everton boards.
