Mikel Arteta has fumed at two refereeing decisions that denied his side a penalty and a late equaliser during Arsenal's 1-0 defeat by Aston Villa on Saturday night.
John McGinn scored the only goal of the game, to help send the midlands outfit to third in the Premier League, just one point behind Arsenal, with the Gunners suffering their second defeat of the season.
But many Arsenal fans felt aggrieved at full-time, with referee Jarred Gillet failing to award them a second-half penalty after Douglas Luiz kicked Gabriel Jesus inside the penalty area, bringing his Brazil team-mate to the ground.
