Could do little about PSG's opening goal as he was pulled out of position by Maxwell's foray forward. Pulled off a marvelous double save to keep out Ibrahimovic's penalty late on.
The defender was rested at the weekend against Xanthi so he would be fit to play tonight and he performed well in the first half before dipping after the interval.
Picked up a yellow card for a cynical block on Lucas and was caught out of position far too often as PSG took control of the game in the second half.
The Spaniard looped a stunning volley against the post in the first half and was dangerous for the home side before being replaced by Saviola.
More defensive than his fellow fullback, Maniatis was diligent defensively to track the runs of the overlapping Maxwell, although he did lose his man when PSG took the lead and was pulled all over the shop by Lavezzi late on.
Controlled the tempo of the game in midfield for the home side initially, but faded, as did his team, as time wore on.
The former Monaco defender had a huge task on his hands against Ibrahimovic and Cavani and he did not rise to the challenge as PSG ran riot after the break.
The central midfielder hassled and harried PSG's midfield brilliantly in the opening half but made a succession of errors as his side lost their grip on the game. Conceded the penalty late on for a foul on Ibrahimovic and twice failed to track Motta for the second and third goals.
Came within a whisker of giving the hosts the lead in the very first minute with a thunderous effort that crashed off the bar before equalizing with a magnificent individual goal. Caused all sorts of trouble early on but saw little of the ball in the second half.
Had no real chance to get himself on the scoresheet and was too often caught offside as his team saw less and less of the ball.
Playing off Mitroglou he helped the likes of Weiss and Fuster flourish by pulling defenders out of position. Withdrawn in the second half for Campbell.
Had his woodwork to thank for keeping Olympiakos out in the first 25 minutes before Weiss scored his fine individual goal. Had little to do during the rest of the match.
Uncharacteristically sloppy for the visiting side in the first half an hour but regained his concentration after Weiss' equalizer.

Questionable defensively, he did not inspire confidence when up against the likes of Fuster and Weiss. As has often been the case since his move from the Eredivisie he looked decent going forward but that is not enough at this level.
The 19-year-old looked shaky on his debut for the Ligue 1 giants, despite playing alongside one of the best defenders in the world in Thiago Silva. Was comically nutmegged by Weiss when the Slovakian made it 1-1. Nodded home PSG's fourth late on.
Played a key role in PSG's opening goal when he ghosted in from the left and flicked the ball into the path of Cavani for an easy finish. A threat going forward throughout.
Looked rattled against Olympiakos' midfield in the first half but like many of his teammates appeared to shift through a couple of gears after the interval. Scored PSG's second and third goals with identical headers.
Improved dramatically after the interval as PSG grew into the game. His strength in the air and on the ball helped the visitors turn the game on its head.
Was ambitious with his passing from central midfield and at times this made him look wasteful in possession.
Hauled off at the break after a disappointing showing on the right-hand side.
Took his goal well early on, and looked dangerous throughout the match. In the second half he forced Roberto into a smart stop low to his left with a driven shot from an angle and linked well with Lavezzi.
Slid a delightful pass into the path of Maxwell in the buildup for his side's first goal, but apart from that had little say in proceedings in Piraeus but for a missed penalty late on. Too often complained about the decision-making of his teammates.
