Boocock, chairman of the Leeds United Supporters' Trust, said: "They are very selfish, very stupid, very badly advised, or all three.
"If they are supposed to be a team and to be united then this does not show it, and as far as I'm concerned, they have missed an opportunity here.
"They could have stood up and said `yes, we have a part to play in this downfall' because their performances on the pitch in the last five matches have been pitiful.
"Do they not realise that some of them earn more in a year than some people do in 150 years? I know Mark Viduka earns more in a week than I do in three years.
"They had a chance to show real Dunkirk spirit. It would have made a huge difference if they had backed the club the way we have backed them."
