Sir Alex Ferguson has launched an astonishing tirade at "wee club" Newcastle and their manager Alan Pardew, who he accused of being "the worst" at haranguing referees.
The Manchester United boss also accused Pardew of "forgetting the help" he offered him at difficult stages of his managerial career.
Ferguson marched on to the pitch on Boxing Day to condemn referee Mike Dean for awarding Newcastle's second goal in United's 4-3 win.
Dean confirmed yesterday he would not be reporting Ferguson, even though the chief confronted not only the referee, but also the fourth official and assistant referee.
Ferguson insists he did nothing wrong, and defended his conduct, admitting he was "an emotional guy".
Manchester United boss Sir Alex Ferguson has hit back at Newcastle manager Alan Pardew, describing the Magpies as "a wee club from the North East".
Pardew said yesterday that referee Mike Dean may feel "slightly disappointed" that he didn't take action against Ferguson after their on-field confrontation during the Red Devils' 4-3 win over the Magpies at Old Trafford on Boxing Day.
Dean did not mention the incident during his match report, and as a result Ferguson will not face any punishment from the Football Association.
Ferguson today hit back at the Newcastle boss during his pre-match press conference ahead of United's home clash with West Brom.
He said: "Alan Pardew has come out and criticised me. Alan Pardew is the worst at haranguing referees. His whole staff, every game. He was at it the whole game on Wednesday.
"He shoves the referee and makes a joke of it, and he's got the cheek to criticise me. It's unbelievable. He forgets the help I gave him, by the way.
"I think the press have had a good field day out of it. They've addressed every possible avenue, the only one they've left is Barack Obama. He's too busy.
"It is unfortunate I carry that, because I'm the manager of the most famous club in the world. I'm not like Newcastle, a wee club in the north east."
Pardew was given a two-match touchline ban and fined £20,000 after accepting an FA charge of improper conduct for pushing an assistant referee earlier this season.
