Earlier this week United lost their legal challenge against the Premier League after an arbitration panel dismissed their claim for a new disciplinary commission to look at West Ham's punishment for breaching league rules on third-party agreements regarding Argentineans Tevez and Javier Mascherano, who is now at Liverpool.
"They seem to be hiding and have no sense of shame. There has been a loss of integrity in our national game," he said.
"The board of the Premier League should stand up and be counted. There is something wrong in our sporting society if they can't sort out a very clear sporting injustice.
"West Ham have got away with it. The Premier League sit there making statements as if they are in the right when they have actually made a mess of it.
"You'd have thought the men responsible for creating this saga would hold their hands up.
"But that doesn't seem to be in their minds. They just hide behind the wall of the legal system rather than accept a duty of care.
"The responsibility for this whole affair rests with the board of the Premier League, not Sheffield United."
