Everton are still angry over Jack Rodwell's red card - despite winning their appeal.
Ref Martin Atkinson's blunder could ultimately cost Everton millions.
At the time of Rodwell's dismissal, the score was still 0-0.
Chief executive Rob Elstone said: "We don't know if the decision cost us one or three points. But at nearly £1million a place in Premier League prize money, it could prove a really expensive mistake."
