The hosts were given a lifeline in the first minute of stoppage time when Oxlade-Chamberlain pounced on a clearing header before curling home, but their celebrations were short-lived as Ferreira-Carrasco finished emphatically.

Monaco had scored only four goals in their six group stage matches and it was not hard to see why as Brazilian defender Wallace and Tunisian Aymen Abdennour were towers at the back.

Arsenal have shown plenty of resilience themselves over the years to come back against the odds, but will have to surpass themselves to save the tie now.
