Jurgen Klopp's players will wonder what hit them as the French powerhouse proved ruthless in front of goal as they took apart the visitors' woeful defenceOlympique Marseille made light work of German champions Borussia Dortmund, dispatching the visitors from Stade Velodrome 3-0 to top Group F with six points from two games.
The hosts took the lead half-way through the first period after a defensive howler allowed Andre Ayew to calmly slot past the helpless Roman Weidenfeller.
Didier Deschamps' men did not stop there, however, as they netted two more goals in the second half with the winger completing his brace from the spot shortly after Remy doubled Marseille's advantage.
The fans in the stadium had to settle for a snore festival in the first twenty minutes of the game as the only dangerous situation in this period was settled by a clumsy attempt to hammer a Jeremy Morel cross, which resulted in the Argentinian kicking the air.
Dortmund were first to threaten to open the scoring as Mario Gotze forced a brilliant double save by Steve Mandanda, who twice denied the Germany international from inside the box. Just as things were looking up for the visitors, a quick break by Olympique Marseille undid their efforts.
In the 20th minute Remy took advantage of a slip by Neven Subotic to release Ayew, who converted with a composed low finish from the left side of the box, leaving Weidenfeller a mere spectator as the ball crept into the right corner.
The goal gave the hoss much needed confidence as they started to press hard for a second strike. However, it was Dortmund who nearly equalised just before the half-hour mark as Mandanda pulled off a great reflex save to block a header by captain Sebastian Kehl, but could only watch as Hummels narrowly place a good volley over the bar.
Still, Marseille were on the rise and nearly made it two in the 36th minute, when yet another swift counter-attack saw Ayew released in a one-on-one with Weidenfeller, but the goalkeeper prevailed on this occasion, making a good save.
The second half saw Dortmund pick up their game and many of their fans were wondering how come Gotze did not level the proceedings as the youngster twice failed to slip the ball past Mandanda, who was having an inspirational game.
Things turned from bad to worst for the German champions as an uncharacteristic mistake by ex-Bayern Munich man Mats Hummels in the 63rd minutes allowed Remy to race on goal, and slot the ball in the right corner, under no pressure whatsoever.
The visitors received yet another sucker punch six minutes later, when the referee awarded a rather soft penalty for a foul by Kehl on Remy. Ayew converted with ease, putting the cherry on the cake and effectively ending the game as a contest.
Dortmund tried to fight back in the remaining minutes, but Marseille showed class and kept their calm, preserving the result until the final whistle.
The only black spot on the hosts' performance was substitute Jordan Ayew's silly sending off in just ten minutes as he picked up two yellow cards and had to be dragged away from the pitch just before the final whistle.
Following tonight's result, Olympique Marseille top Group F with six points, while Dortmund are third with just one. Didier Deschamps' men next game in the Champions League is at home against Arsenal in three weeks, while BVB visit Olympiakos on the same day.
