The Catalan giants have won one and lost one so far in Europe too, and were narrowly beaten by reigning champions PSG in their last Champions League outing a few weeks ago.
Olympiacos are winless in their opening two European clashes, having lost against Arsenal and also drawn 0-0 against Cypriot side Pafos FC.
Jose Luis Mendilibar's side are heavy underdogs heading into this one and will have their work cut out in keeping Barca's plethora of attacking stars quiet across the 90 minutes.

Barcelona vs Olympiacos: Champions League preview
Barcelona are heavily backed to succeed in this season's UEFA Champions League, especially given the attacking talent at their disposal.
Superstar Lamine Yamal continues to reach new heights every week and after recently returning from a short time on the sidelines, the young Spaniard will want to make amends in Europe on Tuesday.
The big news continues to be around further absentees in Hansi Flick's squad, with Robert Lewandowski and Raphinha both currently out of action for Barca.
And with El Clsico to come at the weekend, it remains to be seen whether Flick opts for caution or goes heavy with a full-strength side in this contest.
Olympiacos are yet to emerge victorious this season in Europe and will be hoping for a break after facing Arsenal and now Barcelona in back-to-back fixtures.
The Greek side are second in their domestic division, trailing current league leaders PAOK by one point after seven games played.
Expected to be without full-back Rodinei and winger Gabriel Strefezza due to injury, star names Nikos Botis, Remy Cabella, Ruben Vezo, Yusuf Yazici, Gustavo Mancha and Konstantinos Angelakis are all ineligible too after being left out of their European squad.
FourFourTwo's prediction
Barcelona 3-0 Olympiacos
Barcelona are likely to have too much firepower for Olympiacos to deal with and FourFourTwo believes it will be a routine home victory for the experienced European veterans on Tuesday, with Yamal to score one of the goals.
