Fergie: penalty call diabolical April 26 2008
Sir Alex Ferguson rounded on referee Alan Wiley after Manchester United's title charge was derailed at Stamford Bridge.
The United manager was furious that a penalty was awarded against Michael Carrick with four minutes remaining.
Blues midfielder Michael Ballack kept his cool to score his second goal of the game from the spot and put Avram Grant's team level on points with the leaders.
Wayne Rooney seemed to have secured a point after he cancelled out the opener from the German star.
But Ballack had the final word, leaving Ferguson questioning whether the west Londoners should have ever been given the penalty.
"It was absolutely diabolical, " he told MUTV. "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."
The veteran Scot believes his players have not been getting the rub of the green from officials.
He said: "If we're not getting the decisions we deserve then we're going to have to perform really well.
"In the context of today, when (Cristiano) Ronaldo comes on, in the first minute he's grappled to the floor by Ballack. It was a clear penalty kick but no penalty was given."
Ferguson was also upset by a challenge by Didier Drogba on Nemanja Vidic, which saw the Red Devils defender come off after 14 minutes. The Serbian needed stitches and lost a tooth.
"He got kneed in the face by Drogba - no foul given, " said Fergie. "He was dazed rather than concussed."
Ferguson maintains United are still in the driving seat - given their superior goal difference - with two games remaining. They face West Ham next Saturday before Chelsea travel to Newcastle two days later.
It could even come down to the last game. The champions go to Wigan on May 11 while their title rivals face Bolton.
Ferguson said: "It's still in our hands. The players and the support are really fired up for the next game. Hopefully we can get the result we want.
"In fairness, Chelsea were the better team in the first half. Sometimes, coming out of a European game, it takes a while to get it right. Unfortunately, it didn't happen for us."
