Aston Villa's Diego Carlos was lucky escape a possible red card after appearing to elbow Eddie Nketiah during the Villains win over Arsenal.
John McGinn netted a seventh-minute winner as Aston Villa made it 15 home wins in a row in victory over the Gunners.
A win that sees Unai Emery's men go within one point of their opponents in the Premier League's top four.
Yet, they should count themselves lucky they didn't finish the game with ten men, after the off-the-ball incident involving the Brazilian defender.
