The Gunners beat the Red Devils 3-1 in dramatic fashion thanks to two late goals by Declan Rice and Gabriel Jesus.
Rice netted in the 96th minute before the Brazilian striker wrapped up the three points eleven minutes into injury time to spark wild scenes at the Emirates Stadium.
But things were just as jubilant in the Channel 4 newsroom with an employee seen jumping for joy in the background of the 6pm bulletin.
As the news reader wrapped up the show, an employee rose from behind his computer screen to punch the air with delight.
Viewers were left in hysterics, one said: “This is brilliant.”
A second commented: “Every Arsenal fan in the world.”
More joked: “Didn’t realise Piers Morgan worked at Channel 4.”
Another added: “Being an Arsenal supporter isn’t good for your health. Rollercoaster emotions.”
The Channel 4 worker was one of the luckier Gooners to watch the incredible comeback win after some fans were seen already out of the stadium when Rice netted his winner.

Fans were left fuming during the clash as Kai Havertz missed a sitter and then saw the penalty he won overturned by VAR.
But all were singing come the final whistle as “Rice Rice Baby” was belted out from the stands as Mikel Arteta’s side made it ten points from four games.
Meanwhile, Man Utd have accumulated just six so far this season.
