Manchester City striker Erling Haaland was ready to take on Arsenal defender Ben White after the final whistle.
With the match won 4-1, Haaland sought out White before ref Michael Oliver diffused the row.
White had first approached City midfielder Phil Foden, with the pair squaring off before Bernardo Silva stepped in. Haaland then appeared on the scene.
Haaland and White were pulled apart by teammates as Oliver ushered both sets of players down the players' tunnel.
