Arsenal crashed out of the Europa League as Youssef El-Arabi's late strike in extra-time secured a stunning 2-1 victory for Olympiacos, who progressed to the last 16 courtesy of the away goals rule.

Pierre-Emerick Aubameyang, who remarkably missed a golden chance in the final seconds after El Arabi's winner, had seemed to settle the contest in Arsenal's favour with seven minutes of extra-time remaining with a stunning acrobatic effort.

But Olympiacos, who cancelled out Arsenal's 1-0 lead from the first leg thanks to Pape Abou Cisse's header in the second half, chose to write their own script as El-Arabi bundled in Giorgos Masouras' cross at the Emirates Stadium.

Yet the drama was not finished there – Aubameyang somehow slicing wide of a gaping goal from point-blank range as Olympiacos held onto a famous triumph in a last-16 tie that finished 2-2 on aggregate.
