Antony's reaction after being told to go and play left-back was spotted by fans in Manchester United's 1-0 defeat to Arsenal.
United were condemned to a 19th loss in all competitions after Leandro Trossard scored the only goal of the game in the first half.
With two games remaining in the Premier League, United are in eighth place and require two wins to avoid experiencing their worst ever season in the Premier League.
But £86 million signing Antony has been panned online after a video showed his antics in the second half.

The Brazilian, who has one goal in the Premier League this season, came on as a substitute and replaced Amad Diallo in the 70th minute.
He had been playing on the right flank but then by the 87th minute, Antony was switched over to left-back when Omari Forson was thrown on in place of Aaron Wan-Bissaka.
And in a video doing the rounds on social media, the former Ajax man did not do a good job of hiding his true feelings.

Antony looked furious as Christian Eriksen and Scott McTominay pushed him into position.
McTominay then made a point of motivating Antony but he didn't look interested in the slightest.
He could then be seen in conversation with compatriot Gabriel Jesus, with both covering their mouths as they spoke.
It was a similar reaction to Antony's headloss against Liverpool when he was moved to the left side of defence.

The 24-year-old was once again slammed by supporters for his petulant behaviour.
One fumed: "I’ve never, ever, EVER disliked a United player this much."
A second added: "Honestly might be the most unlikable player I’ve ever come across. Offers absolutely nothing for us and consistently poor yet moans at everybody else."
A third agreed: "God he’s absolutely rancid, I’ve never hated a player for United so much."

A fourth observed: "Looks like he's slagging off our manager to an opposition player. His attitude stinks."
Another fan said: "Antony is pound for pound the worst signing this club has made, and there's been some bad ones."
