Arsenal secure a big 3-1 win over Olympiakos in Europa League
Arsenal took the lead in the first half through Martin Odegaard, who opened his account for the Gunners with a thunderous effort from range.
But Arsenal repeated their performance against Burnley by giving the ball away just outside their area, gifting Youssef El-Arabi an easy opportunity to score.
Arsenal battled back ten minutes before the end to put themselves in the driving seat for the second leg at the Emirates, with Gabriel scoring his first goal in Europe to secure the win.
Elneny put the cherry on the icing with another long-range effort late on.
