Despite being beaten pretty easily for two goals, Reina produced a performance he'd be content with. Efficient at the back.
Poor decision making hindered Armero's successes against Marseille. Sloppy at the back and going forward, too, as highlighted by his late miss.
Like Fernandez, Albiol also excelled against a threatening Marseille attack. Limited their advances towards the end of the first half and the second.
Fared brilliantly up against Jordan Ayew and Mathieu Valbuena, reading the game well to intercept speculative passes, and using his strength to keep Ayew out of the game.
The Swiss international was the star in the middle of the pitch with a brilliant performance. Defensively sound, he ensured OM enjoyed very little success with his combative style. Also helped that he scored a brilliant volley in the first half.
Didn't have a major impact in this game after being given the runaround by Mathieu Valbuena. Nevertheless, wasn't too bad either.
Handed a start in midfield and didn't disappoint with a solid, if unassuming game in the middle. Competent on the ball and dictated play well.
The star of the evening. Scored his first two goals against a French side, and they were both of brilliant quality. Put Marseille to the sword completely tonight.
The former Madrid winger had a sustained impact against Marseille this evening, winning virtually every duel with Kassim Abdallah. A threat out wide.
The Belgian winger was another that gave OM a defensive headache. Utilised the gaping pockets of space behind the defence to operate in, and teed up Higuain for his second.
Didn't make as much of an impact as his team-mates, but nevertheless, Pandev fared well, if only, in brief occasions.
The OM captain made one or two crucial saves to keep Marseille in the game when it mattered most.
The veteran defender struggled up against Dries Mertens, being beaten for pace, but improved as the game wore on, especially midway through the second half.
The highly rated centre-back has been much criticised this season, but tonight, he was a solid performer, frustrating Higuain and co. as best he could. Nevertheless, defensive positioning remains a major issue.
Rather inconsistent tonight, but marginally better compared to previous games, the left-back was a potent threat on the wings, but at the back, suffered a lot more.
The right-back was handed a full Champions League start after injury to Rod Fanni, and he failed to impress. Defensively, he was no match for Napoli.
The U20 World Cup winner was handed his first CL start this evening, and he starred for OM from first whistle to last. A devastating prospect on the wing, he picked up a goal and assist. Could hold onto starting role.
The experienced Cheyrou was preferred to the youthful and more technical Imbula this evening, but Cheyrou provided a rather industrious game in midfield, with varying levels of success.
The Togo midfielder fared decently in the middle of the park, contributing well to OM's short and quick passing manoeuvres. Tired as the game progressed and influence waned.
The France international was again the creative hub just behind the striker, but saw his influence fluctuate greatly. Gave Christian Maggio a few problems with his trickery.
Jordan Ayew endured a torrid evening up front, having not been afforded a great deal of service. Kept in check by Fernandez and only had intermittent success.
The elder Ayew brother starred also for OM this evening, highlighting his superb versatility. Functioned all over the midfield, and linked up with his team-mates well.
