Arsenal failed to qualify for the Europa League quarter-final after they lost 5-3 on penalties to Sporting Lisbon on Thursday night.
Gabriel Martinelli’s shot was saved from the spot to allow the Portuguese side to progress to the quarter-finals.
Both sides had drawn 1-1 on the night and 3-3 on aggregate.
Even before the shootout, which the visitors won 5-3, it was a second leg that had it all.
Arsenal had looked on course to qualify relatively comfortably when Granit Xhaka tucked in the rebound from Martinelli’s first-half shot but the Gunners failed to fire at all in the second half and were pegged back in sensational style by Pedro Goncalves’ outrageous lob from the centre circle.
Manchester United beat Real Betis 1-0 in Spain to progress with a 5-1 aggregate.
