Arsenal's Champions League hopes lie in tatters at the last-16 stage yet again following a first-leg 5-1 battering at Bayern Munich.
The Gunners, who have been eliminated in the first knockout round of the competition in each of the last six seasons, twice by Bayern, not only conceded five goals but over 75% possession in Germany.
Their challenge lasted until the break thanks to Alexis Sanchez, who followed up his own missed penalty to equalise after Arjen Robben's superbly-struck 25-yard opener.
But after Arsenal lost Laurent Koscielny to injury early in the second half, Bayern ran riot during a 10-minute period in which Robert Lewandowski headed home before Thiago Alcantara scored twice. Substitute Thomas Muller rubbed salt in the wounds with a late fifth.
It leaves Arsenal with a near impossible task in the second leg and heaps more pressure on manager Arsene Wenger, who now only has the FA Cup as a realistic source of silverware in what will go down as another failed season.
