A damning video shows Jordan Ayew shoving Fred in the face before Casemiro received a straight red card during Manchester United vs. Crystal Palace.
Man United returned to winning ways in the Premier League by picking up three points against Palace at Old Trafford.
Bruno Fernandes opened the scoring from the spot, with Marcus Rashford doubling his side's advantage after the hour mark.
But the Red Devils' victory was marred as Casemiro picked up a red card following a brawl, which saw him put his hands around Will Hughes' neck.
However, Man United fans on social media have pointed out Ayew's actions during the melee, which resulted in no punishment.

He's seen shoving Fred in the face amid the wild scenes between both sets of team.
People online want the Palace forward banned as they slammed the inconsistently of the officiating following the Brazilian's dismissal.
One Twitter user wrote: "That’s even worse than Casemiro’s, so much force in that strangle."
A second tweeted: "And look at the force Ayew applied and compare it to the force Casemiro used. It’s really poor from VAR."
A third added: "If Casemiro gets a 3 match ban I hope Ayew gets the same punishment as well. Keep the consistency."
A fourth said: "And the officials ignored that."
Another commented: "How has Ayew got away with this????"
As a result of his red card, Casemiro will miss Man United's next three domestic games. He'll be unavailable for the back-to-back league games against Leeds United as well as Leicester City.
The 30-year-old will be available for selection when Man United face Newcastle United in the Carabao Cup final.
Speaking after the game, Erik ten Hag admitted Casemiro 'crossed the line' with his actions as he bemoaned the inconsistency as he appeared to reference Ayew's shove.
"Casemiro crossed the line; you saw that. However, I’m unhappy with the inconsistent refereeing; not only this game but also in Palace. They elbowed Martínez and last week with Eriksen," he said after the 2-1 victory.
"A lot of other players crossed the line, including some Crystal Palace players. VAR didn’t intervene with them."

Utd are suffering with refs decision but nobody sees that because we are winning games. ETH needs to start talking more about it to get the attention of FA. Against Reading and Palace both legs

tbh Casemiro was just trying to stop the player from fighting and is rather unfortunate for him that his hands grab him on his neck and he wasn't even looking where he was placing his hands and even the guy wasn't even paying attention to Casemiro because he didn't even feel the touch , he was just unlucky there
