Fergie was thrilled at seeing his side come back from 3-0 down to draw the game 3-3, but he vented his anger at Darren Cann who was the referee’s assistant who failed to spot a foul from Gary Cahill on Danny Welbeck when the striker raced through on goal.
Cann and Ferguson have been in disagreements before, none worse than when he flagged for penalties against his side when they played 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."
