Arsene Wenger's body language said it all about his side's defeat.
Arsenal boss Arsene Wenger could barely look as his side conceded late against Monaco.
Alex Oxlade-Chamberlain had given them a lifeline to bring the 2-0 deficit back to a one goal lead, before a breakaway strike from Yannick Ferreira-Carrasco made the scoreline 3-1 to Monaco.
His reaction on the bench said it all, his head bowed, looking at the floor contemplating where it had all gone wrong.
Moments later that devastation had turned to anger, with the Frenchman clearly seething at his side's inability to concentrate and defend effectively.
Wenger told Arsenal.com after the game he felt his side defended suicidally, but there was poor play across the starting 11, with the man sitting behind him on the bench, Olivier Giroud, partly responsible.
Giroud had attempted six shots but fired them all off target, and was hauled off by Wenger with half an hour to go.
Arsenal need a huge turnaround to qualify for the quarter-finals, and have shot up from 10/1 to win the competition wih SkyBet ahead of the game, to 66/1.
