The defeat was City's second of a hard week, following their 3-0 loss to Liverpool at Anfield, and Danilo has urged fans to get behind the team as they aim for a remarkable comeback of their own when Jurgen Klopp's men visit in three days' time.
"I know they love to attack, they don't like to defend, so I knew I had to get in the box", the Frenchman explained.
RD: It was similar to the first half.
City can win the title in their next Premier League game - away to Tottenham. Pogba was obviously key to the comeback, but so was Alexis Sanchez. "He needed that second half like you wouldn't believe".
The Citizens had only conceded three goals twice this season.
Remember when we brought up all those missed chances by City?
Aguero, who replaced Gundogan in the 76th minute, was Guardiola's most effective substitute on the night and almost pulled things back for City with a header, only for De Gea to pull off a stunning save to deny the Argentine.
The soundtrack of celebration from the first half was now a noise of desperation. Young was lucky with both incidents - either could have gone the other way.
They face Liverpool on Tuesday in the second leg of their Champions League quarter-final tie at the Etihad.
"They found their game, found their actions, they have spirit, but we did everything to win the game. You have to judge the performance and the way they played not only to look at the result make a judgement".
Reds boss Jurgen Klopp made five changes choosing not to risk Premier League top scorer Mohamed Salah.
"Our challenge is to finish second but I want to congratulate City for the title because they are going to win and deservedly", he said. I'm not entirely convinced.
Yet without the league's top scorer Mohamed Salah and Roberto Firmino in a very different starting XI to the one that outplayed Manchester City, Liverpool looked to have the Champions League return on their minds.
In the video below we soaked up the frenzied atmosphere, catching up with excited Man City fans in the build-up to the eagerly anticipated derby, and finding out just what they think of that man Mourinho, along with their pre-match predictions.
Former Wales and Leicester City midfielder Robbie Savage described Pogba's second-half performance as his "best 45 minutes in a Manchester United shirt" and said "big players step up to the mark".
