Andre Villas-Boas and Sir Alex Ferguson both lambasted the performance of the match officials in Sunday's thrilling 3-3 draw between Chelsea and Manchester United at Stamford Bridge.
Chelsea boss Villas-Boas blasted referee Howard Webb for giving Manchester United a second penalty for a dubious foul from Branislav Ivanovic on Danny Welbeck in the box.
Villas-Boas claims Webb's decisions changed the course of the game as Chelsea were cruising towards a crucial victory before two penalties were given against them, and said: "The second penalty was very, very dubious."
