Arsenal centre-back David Luiz was sent off in a one-man horror show at Manchester City after giving away the first goal in the game shortly after being introduced to the action as a substitute.
Luiz was sent on to replace Pablo Mari in the Gunners defence 24 minutes into the first half, and his error gifted City the lead just before the interval.
Raheem Sterling got in behind the Brazilian after he made a hash of controlling a through ball, and he finished past Bernd Leno to fire the home side in front.
Luiz's night got worse when he was dismissed shortly after the restart, having been punished for bringing down Riyad Mahrez when he raced through on goal.
