Ghana forward Ayew struck in each half and France striker Loic Remy was also on target in a lively game to put Marseille firmly in command of Group F with six points from two games.

France keeper Steve Mandanda was also instrumental in the former champions’ win, making a series of superb saves throughout.

Ayew, who opened the scoring in the 20th minute, put the result beyond doubt in the 69th from the penalty spot after Remy had doubled the tally, leaving Dortmund third in the Group with one point.

Marseille’s night finished on a sour note when substitute Jordan Ayew was sent off in stoppage time, picking up a second yellow card for diving.

German champions Borussia got off to a solid start but Marseille looked dangerous on the break, and the hosts went ahead when Andre Ayew, a constant threat on the left flank, was set up by Remy to unleash a low shot past Roman Weidenfeller.

Marseille, who have won only one from eight league games this season, stayed in front thanks to the in-form Mandanda as the France keeper denied Mario Goetze several times with lightning quick saves.

Didier Deschamps’s side doubled the lead in the 62nd minute against the run of play when a Mats Hummels header landed into the path of Remy, who volleyed home from inside the box.

Remy was brought down in the box seven minutes later and Ayew got his second by cooly slotting past Weidenfeller.
