And forward Jeremy Doku, who came on as a substitute, shared a behind-the-scenes video on his social media following the win.

It showed the Man City players bouncing up and down and singing inside their dressing room at Old Trafford.

They could be heard chanting: “Champions again, ole ole.”

Defender John Stones was front and centre in the video as he danced in his full kit.

Meanwhile, midfielder Rodri had taken his top off and was getting stuck into the celebrations.

Jack Grealish also shared a selfie of the players smiling immediately after the win.

And Doku’s clip was not the only post he shared on social media following Man City’s comprehensive victory.

Playing in his first Manchester derby, Belgian Doku was on the end of a kick out from Man Utd’s Antony in stoppage time.

The Brazilian got away with a booking after the pair exchanged verbals on the pitch.

And Doku brilliantly trolled Antony with a post after the game.

He shared an image of the incident and added the caption: “Stay calm… Manchester is blue.”

Man Utd legend Gary Neville ripped into Antony after he lashed out and insisted he would have given him a red card.

He said: “Doku’s absolutely right, Antony just has a kick at him.

“Absolutely right, Doku. United have lost their discipline. That’s absolutely ridiculous, I’d just send him off.

“It’s absolutely ridiculous from Antony, it’s embarrassing.”

Man Utd have now lost five of their opening 10 games of the Premier League season.

Erik ten Hag’s men sit eighth in the table, nine points behind Man City in third – who are two points adrift of league leaders Tottenham.
