Bayern Munich 5-1 Arsenal: Gunners run out of ammo in second half
It is a cliché in football to say it was a game of two halves, but Arsenal's Champions League dreams were alive until the break.
It took just 10 minutes for Bayern Munich to demolish any hope for a Gunners revival after Arsenal lost Laurent Koscielny to injury early in the second half.
Despite being outplayed by the Germans in the first half, Arsenal were still clinging on after Alexis Sanchez cancelled out a stunning strike from Arjen Robben.
The 33-year-old struck a perfect 25-yard shot into the top corner in the 11th minute, following a move which involved nine of Bayern Munich's 11 players.
Arsenal were lucky to be awarded a penalty on the 30th minute, following a clumsy challenge from Robert Lewandowski on Koscielny.
It was poorly taken by Sanchez, forcing Neuer to spill the shot. It took three attempts for the Chilean to finally score, levelling Arsenal against the run of play.
When Bayern returned in the second half, they looked certain to better the 1-1 score that was flattering to the visitors. When captain Koscielny went off injured in the 49 minute, Munich capitalised with a 10-minute period that left Arsenal stunned.
In a simple but effective set piece, Philipp Lahm sent the ball in the box for Lewandowski to rise in the air and to head easily in.
For their third goal, it was a piece of football beauty. Xabi Alonso passed the ball to the previous goal-scorer who hit a cheeky backheel to Thiago, striking the ball coolly into the goal.
It was yet another high-scoring Champions League game where the losing side could have lost by such a considerable amount without their goalkeeper. Despite conceding five, David Ospina stopped a humiliating night from turning into a travesty.
Bayern scored their fourth at the advantage of poor Arsenal defending from a corner. They failed to clear the ball three times before Thiago was ready on the edge of the box, relying on deflections.
Substitute Thomas Muller intercepted the ball from wasteful Arsenal passing to end such a dreadful night for the Gunners, and most likely their Champions League campaign this season.
Arsenal have been eliminated in the first knockout round of the competition in each of the last six seasons - twice by Bayern Munich. It proves the old saying wrong: three times lucky - not for Arsene Wenger's Arsenal, it would seem.
