Arsenal will be hoping to build on their momentum in the Premier League with another victory in Europe on Wednesday night.
The Gunners left it late in the north-east on Sunday evening, as strikes from Mikel Merino and then Gabriel ensured a famous comeback victory for Mikel Arteta's side that may have boosted their title hopes given Liverpool's slip-up at Crystal Palace.
As for Olympiacos, the Greek league leaders are yet to lose so far domestically and saw off Levadiakos 3-2 at the weekend.
A 0-0 draw with Cypriot side FC Pafos began their campaign, but a tough test against Arsenal lies in wait at the Emirates Stadium.

Arsenal vs Olympiacos: Champions League preview
Arsenal will hope to build on their recent 2-0 win over Athletic Club in their prior UEFA Champions League contest, with Gabriel Martinelli and Leandro Trossard both netting in that one.
In fact, the Gunners are on an impressive five-match unbeaten streak in all competitions heading into this one, and making it six would go a long way in building further momentum for manager Arteta.
Kai Havertz, Noni Madueke and Gabriel Jesus will not return from their severe knee injuries before the winter, while deadline-day addition Piero Hincapie is also still sidelined with a groin problem.
Olympiacos' woeful form in Europe doesn't make for pleasant viewing heading into this one, especially given they are set to face one of the Premier League's most feared teams.
Staggeringly, it has been almost exactly 10 years since they last won a Champions League league phase/group-stage match on the road, doing so against Dinamo Zagreb in October 2015.
Remy Cabella and Yusuf Yazici are set to play no part for the Greek giants and both will be huge misses in London on Wednesday evening.
FourFourTwo's prediction
Arsenal 5-1 Olympiacos
Arsenal are in fine form as of late, and after winning at the death against Newcastle at the weekend, Arteta's side should be well up for this one and we are expecting a big scoreline.
