According to reports in the Daily Mail, the Scot was furious with his men for the manner of their defeat at Old Trafford, and gave the Red Devils no doubts over what he thought of their performance, as he also slammed senior squad players for failing to steady the ship against the Citizens.
His ire was also reserved for Patrice Evra and Rio Ferdinand, who he blamed for a lack of organisation after the reigning Premier League champions went down to ten men with the score 1-0 in favor of City.
It was reported that the United manager blew up at his stars in the dressing room just minutes after the loss, calling them "f****** idiots', and demanded that the senior players report to the training ground for an immediate post-mortem.
Ferguson was also upset with club captain Nemanja Vidic, for playing against Slovenia for Serbia earlier this month, despite being out of action for United with a calf injury that kept him out for two months.
The 30-year-old then added fuel to Ferguson's rage by being sent off in United's Champions League win over Romania side Otelul Galati last Tuesday.
Vidic himself admitted that United were unhappy at his committment to his national side, and said as much when announcing his retirement from international football recently, after winning 56 caps.
"The basic reason is that my commitment for the national team has been criticised by the media and therefore by the public as well for some time,' said the Serbian.
"I've been under fire although I turned up to play for Serbia even when I was injured and sometimes against the advice of my club", he added.
The humiliation by City continued for Ferguson even after the game, as the United manager had a nightout planned for his coaching staff, taking them to his favorite hotel. However, some went on to a nearby nightclub, and were flummoxed to bump into several City players who were out celebrating their victory.
Hopefully for the United squad, the manager's anger would have been somewhat assurged by their most recent 3-0 Carling Cup win over Aldershot on Tuesday night, as goals from Dimitar Berbatov, Antonio Valencia and Michael Owen gave them a comfortable win.
