Arsenal have put themselves in a strong position to make the last-16 of the Europa League. They defeated Olympiakos 0-1 and that away goal might be important for the Gunners.
Alexandre Lacazette scored in the 81st minute after a brilliant assist from the youngster Saka.
Arsenal made some mistakes in defense in the first and the second half, but Leno turned out to be the hero of the match with some fine saves.
However, Lacazette has scored an important goal but he missed two great chances to extend the lead.
After Gabriel Martinelli’s brilliant work to beat two defenders at the byline, the Frenchman somehow put the ball wide from seven yards out.
The Gunners extended their unbeaten run to nine games under Mikel Arteta management.
Arsenal will be confident of reaching the next round of the Europa League when they welcome Olympiakos to the Emirates Stadium for next week's second leg.
