Manchester City midfielder Jack Grealish was furious after defeat at Manchester United.
It came after Bruno Fernandes scored a controversial opener that some have argued should have been ruled out, as Marcus Rashford was in an offside position and may have interfered with play.
According to pundit Jan Aage Fjortoft in a video he posted on twitter, there was a frustrated exchange between players in the tunnel after the game.
He claimed Grealish, who scored City's only goal of the game, was "very disappointed" but "not aggressive" as he vented his anger in the tunnel, while Citizens manager Pep Guardiola and United captain Harry Maguire were also "talking a bit".
