Sir Alex Ferguson was angry with the performance of the match officials in Manchester United's thrilling 3-3 draw at Chelsea on Sunday.
United manager Ferguson was thrilled to see his team come back from 3-0 down to steal a valuable point, but he was furious at the performance of linesman Darren Cann, who failed to notice a foul from Gary Cahill on Danny Welbeck after the striker raced through in the first half.
Ferguson has a history of disagreements with Cann after the linesman gave penalties against his team when they were playing Arsenal and Liverpool.
"They should've had a man sent off in the first half," Ferguson said. "Danny Welbeck's clear through and he was brought down. Okay, it's outside the box, (but there was) no decision.
"That linesman, who's given a penalty kick against us from 40 yards away last year against Liverpool, this year against Arsenal - and he can't see that?
"I don't blame Howard Webb - he needed help in that situation and he didn't get it. That assistant referee, who's all too happy to flag at Old Trafford for penalty kicks, didn't give them."
