Manchester United boss Sir Alex Ferguson was furious after seeing a controversial penalty send his side crashing to a 2-1 defeat at Premier League title rivals Chelsea.
A penalty four minutes from time gave the Blues victory, with Ferguson fuming at the ward for a handball against Michael Carrick.
He told MUTV: "It was absolutely diabolical for the penalty. It is a major decision.
"Granted it hit his hand, but he has not lifted his hand above his shoulders, above his head, anything like that.
"It is going straight to Rio Ferdinand. The referee should have seen that rather than the linesman. If we're not going to get those decisions then we are under pressure."
Ferguson also had fresh injury concerns over Nemanja Vidic and goalscorer Wayne Rooney to concern him.
He added: "Vidic has a few stitches under his lip and he's lost a tooth.
"He was dazed rather than concussed, but if we'd waited for him to come round we would have played 10 or 15 minutes with ten men and you can't afford that in such a big game. So we had to take him off.
"Rooney's got the same knock as he got last week, straight on the hip bone.
"It takes a while for that to clear because when you get a bang on it it's very painful. I'm hopeful he will be all right for Tuesday."
