Birmingham City chairman David Gold was far from happy with referee Steve Bennett's performance during Saturday's 1-1 draw with Leicester City.
Bennett opted not to send off Foxes goalkeeper Conrad Logan after he brought down Dudley Campbell while the score was still 0-0, and Gold believes the decision changed the outcome of the game.
"The last time I felt so aggrieved about a refereeing decision was at the Carling Cup final in 2001," he told the Birmingham Post.
"Andrew Johnson was brought down by Stephane Henchoz and everyone in the country knew it was a penalty. Everyone except for David Elleray who couldn't bring himself to point to the penalty spot twice in one game.
"I think the decision not to send off Leicester's goalkeeper was almost as bad.
"It was a cynical foul and the goalkeeper went on to have an outstanding game as he knew it was going to be his day.
"When you consider we have had four red cards this season, it makes it difficult to stomach."
