Olivier Giroud put Arsenal FC in front after just three minutes and, although Bayern largely controlled proceedings from there on in, a Laurent Koscielny header four minutes from time made for a nervous ending with the tie all-square on aggregate. The Bundesliga record title-holders held on however, to go through on away goals.
Ice cold Giroud
In freezing conditions, Bayern were themselves caught out cold at the start when Giroud reached Theo Walcott’s low cross to lift his shot into the roof of the net from point-blank range. A slip from David Alaba contributed to giving Walcott the time and space to pick out the Frenchman in the centre, but Bayern didn't dwell on the early setback and soon set about trying to restore parity on the night.
Toni Kroos stung the palms of Lukasz Fabianski with a shot from 25 yards while Thomas Müller found a way around the back on three times, only testing the Arsenal keeper on one of them though as the hosts heaped on the pressure. Arsenal may have known beforehand that scoring a goal at the Allianz Arena is a risky affront, yet they managed to deal with the consequences well, keeping their riled hosts at arm's length up until half time.
Inside three of the restart, Arjen Robben and Kroos had both placed shots within inches of the post. Robben’s propensity to shoot on sight was becoming a thorn in the side of the Arsenal defence. However, he scuppered Bayern's best chance of the encounter midway through the second half when Fabianski pushed his effort wide after a sublime backheel from Müller had carved open the Arsenal defence.
Further chances followed, but, frustratingly for Jupp Heynckes' troops, the north London outfit's goal remained intact. Arsenal substitute Gervinho almost set up a grandstand finish when he popped up in the Bayern penalty area, only to poke the ball agonisingly wide of the far post.
Bayern do not have the best of memories of facing English sides at the Allianz Arena, and after the disappointment of last May’s Champions League final defeat to Chelsea FC, the sight of Koscielny netting a second for the Gunners from a rare corner to leave them within a goal of progression revived unpleasant memories.
The runaway lague leaders dug in though and saw out the final few minutes, to remain on course for a possible season treble as they join Borussia Dortmund in the draw for the quarter-finals on Friday (12:00 CET).
