Pogba was dismissed in the 74th minute of Saturday’s 3-1 victory for his challenge on Gunners defender Hector Bellerin.
After the match, United manager Jose Mourinho expressed disquiet at the decision, saying Pogba was ‘frustrated’ at the reaction of some of the Arsenal players to his challenge.
But former Premier League referee Dermot Gallagher told Sky Sports: “Where he went was dangerous with excessive force.
“Without doubt it’s a red card.”
Pogba created two of United’s three goals at the Emirates but he will now have to sit out Sunday’s crucial game against Manchester City – who went eight points clear of second-placed United when they beat West Ham 2-1 on Sunday.
The Frenchman will also be banned for the visit of Bournemouth next Wednesday and the trip to West Brom on 17 December.
