The worst part for me is the fact that the Reading players/manager just went along with it. If they were my team, I'd have instructed them to let Watford score straight from the kick-off so it was level again. Very poor sportsmanship.
Still, it was funny though. Apparently the linesman who made the decision is going to be "receiving operational advice". I presume this is ref-speak for "sent to the Blue Square Conference Southern Division"
