After a couple of decent saves, his moment of madness proved the spark that ignited PSG's resurgence. Gifted les Parisiens the equaliser with a terrible fumble.
Like N'Koulou, managed to carry out his defensive duties well, keeping PSG at bay for the majority of the first half. Found it difficult after the break.
The 19-year-old fared well on the flanks, especially defensively, but it was a rather inconsistent performance in the second half, with the youngster guilty of not focusing his deliveries centrally.
The defender was a powerful presence on the right, constantly getting down the wing and linking with the forward players. His defensive work left a lot to be desired, though.
Improved a lot after his indifferent start to the season. A rock at the back, as OM consolidated their lead. Not at fault for either goal, but struggled in the second period.
The Togo midfielder endured a tough time, though he did fare well in the middle of the park, in front of the defence. Found it increasingly difficult, though, as PSG grew in strength.
Winning the penalty that earned Marseille the lead, the winger was in unusual feisty form tonight. His team-mates weren't on the same wavelength as him, despite his good performance, and for that reason wasn't as influential as expected.
Linked with Chelsea earlier in the day, Imbula was a solid performer, and showed exactly why he is held in high regard. Great vision and a good passer of the ball. Subbed off in the second half.
Given a start ahead of Andre-Pierre Gignac, the much-maligned Ayew was a menacing presence in the first half, bringing a fantastic save out of Sirigu.
Unable to really recapture his early form for his new club, but a highlight was a stunning strike that Sirigu was required to parry. Inconsistent at best.
The Ghana international scuppered any hopes of Marseille salvaging something from the game. Gave away a stupid penalty, undoing any good he managed in the encounter.
The Italy international was a star in the PSG goal, producing a string of fantastic saves to keey OM at bay. Beaten only by a penalty, Sirigu was on top form to deny Ayew, Valbuena and Payet.
G. van der Wiel
A much improved van der Wiel is reaping the rewards for PSG, with another decent performance. Linking superbly with the midfield and making well-timed runs. A constant threat.
Playing in his first Classique, the young defender more then held his own at the back, providing some decent clearances. Won the penalty that decided the game.
Consistently reliable, or reliably consistent? Maxwell once again highlighted his worth with a well-taken goal, coming in off the left wing to challenge Mandanda - and win.
A top performance from Alex, who was overworked in the second half as OM sought to regain their lead. Marshalled the forwards well, though, and dealt with nearly everything OM threw at him.
Saw his evening curtailed with a rather clumsy penalty given away to Marseille for a challenge on Valbuena. But, in truth, didn't deserve the red card.
Matuidi continues to go from strength to strength, and epitomises PSG's rise. A stunningly confident player who can threaten from first minute to last. A thorn in OM's side.
The young Italian had this week said he worked on his discipline, but was in a tussle with Valbuena from the off. Discipline aside, worked well in midfield to aid PSG.
The Argentine showed some decent touches but saw his evening curtailed after being sacrificed after Motta's red card.
Didn't really get the rub of the green once more, and struggled against N'Koulou. Still cannot nurture the partnership with Ibrahimovic but, like the Swede, earned a pathetic booking.
May have got the winning goal but Ibrahimovic didn't shine as expect, despite doing well to involve himself more with the approach play. Booked for wasting time.
