Manchester United winger Antony appeared to be furious at manager Erik ten Hag on Sunday.
The Red Devils earned an impressive 4-3 win over Liverpool in the FA Cup quarter finals at Old Trafford.
Antony, who came on as a sub and scored in the game, was asked to play left-back in extra-time by Ten Hag.
Footage showed the Brazilian looking confused and gesticulating with his hands after the team huddle.
He then spoke to Marcus Rashford, with his teammate offering him advice.
