Arsenal and Olympiakos square off for the fourth time in the last two years in the Europa League knockout stage on Thursday.
The Greek giants will look to repeat last season's late-match heroics against Arsenal after Youssef El-Arabi's extra-time goal sent Olympiakos through on away goals. But this year Olympiakos has a much bigger mountain to climb after the Gunners scored three away goals in the first leg last week.
Tied at 1-1, Arsenal secured two goals from the unlikeliest of sources—defensive midfielder Mohamed Elneny and center-back Gabriel—in the final 11 minutes to give themselves a comfortable cushion heading back to the Emirates Stadium, where even a potential 2-0 Olympiakos win won't be enough to eliminate the Gunners.
