Arsenal and Olympiakos have been drawn together in the Champions League on four occasions since 2009.
The Gunners have won all three of their home games against the Greek giants, but they have lost on each of their three trips to Athens.
Olympiakos come to North London on Tuesday night as big underdogs in the eyes of the bookmakers.
Ladbrokes, Coral, William Hill and BetFred all make the Gunners 2/5 favourites to claim three points at the Emirates Stadium.

Despite what the bookies think, Olympiakos should not be underestimated. As previously mentioned, they have beaten Arsenal three times in the past six years.
Furthermore, Marco Silva’s men are in fine form domestically right now, having won their first five games this season by a 16-3 aggregate score.
While Arsenal fans will be hoping the likes of Alexis Sanchez, Mesut Ozil and Santi Cazorla prove too strong for their opponents on Tuesday night, Olympiakos also have a fews stars in their ranks.
Here, we identify five Olympiakos players to look out for…
5. Esteban Cambiasso
Olympiakos will have to keep the ball well if they are to avoid being overrun by Arsenal.
Thankfully, they have one of the world’s top passers in midfield. Cambiasso has been known to score the odd spectacular goal too.
4. Ideye Brown
He became West Bromwich Albion’s record signing in 2014 when he joined the Baggies for £10m, according to the Daily Mail. He left the Hawthorns a year later, having scored seven goals in all competitions.
The 26-year-old striker has yet to find the net in four games since arriving at Olympiakos last month, but he has the pace to worry Arsenal’s defence, especially Per Mertesacker.
3. Dimitris Siovas
As well as being a threat on the counter-attack with their pace, Olympiakos will pose a threat from set-pieces.
Centre-back Dimitris Siovas won’t be taking them, but, at 6ft 3in, he is likely to be the main target of corners and indirect free-kicks.
2. Kostas Fortounis
Fortounis is the leading scorer for Olympiakos this term, with four goals in five Greek League games.
He operates in midfield and is dangerous from long range, but his main scoring threat comes from his well-timed runs from deep.
1. Pajtim Kasami
Ultimately, Olympiakos are likely to require a moment of magic if they are to upset Arsenal at the Emirates.
Former Fulham midfielder Kasami is certainly capable of coming up with something special. Remember this?
