Manchester United fans believe Erik ten Hag made a 'sackable offence' in their crushing defeat at Nottingham Forest on Saturday.
Forest beat Man United 2-1 at the City Ground to condemn more misery on Ten Hag as the pressure mounts.
Nicolas Domínguez opened the scoring just after the hour mark as Marcus Rashford levelled proceedings in the 78th minute after a huge error by Matt Turner.

Nuno Espirito Santo's side regained the lead through Morgan Gibbs-White, who curled home a stunning strike in the 82nd minute.
But before the hosts took the lead for the first time, Ten Hag made the decision to take off Kobbie Mainoo at the break with the game goalless.
The Dutchman replaced the 18-year-old with Scott McTominay to the dismay of Man United fans on social media.
They couldn't believe his substitution as they made their feelings known.
One X user exclaimed: "That’s a sackable offence."
A second wrote: "If Mainoo ain't injured then I want Ten Hag sacked on the spot. Don’t even wait until full time."
A third added: "TEN HAG OUTTTTTT!!!! THAT IS A CRIMINAL SUBSTITUTION."
A fourth fumed: "That McTominay for Mainoo sub is going to haunt me for weeks. Where’s the plan here? It’s so poor."
Another commented: "Mainoo off for McTominay is an example of bad game management."
Man United have now lost a staggering nine league games this season as they failed to climb above sixth-placed West Ham United.
They resume their league campaign on January 14 when they entertain Tottenham.
