City captain Vincent Kompany rose highest from a David Silva corner to emphatically head past David De Gea on the stroke of half-time to seal a vital three points.
The result moves Roberto Mancini’s side ahead of Manchester United on goal difference although City face a testing trip to St James’ Park to face Newcastle United on Sunday.
“Yes, they’re in the driving seat now,” said Ferguson. “They only need to win two games of football [against Newcastle away and QPR at home].
“It’s not over. As long as there are games of football to play, it’s not over of course.
“We have the same number of points but they have an eight goals advantage and that’s a big advantage of this time of the season.
“I think we have to look at last Sunday as the bad result for us, the Everton game.”
Ferguson reacted with fury when City substitute Nigel de Jong caught Danny Welbeck with a late challenge in the second half, leading to a heated exchange between the Red Devils manager and Mancini on the touchline.
The Netherlands midfielder was shown a caution for his reckless tackle but United’s 70-year-old boss was critical of his counterpart’s behaviour in his technical area.
“Mancini was badgering the referee the whole game, the fourth official and the linesman. The minute I go out there, he’s off again,” said the United manager.
“He was complaining about referees the other week. He can’t be complaining tonight, that’s for sure.”
