Helped by a brace from former Lille man Dimitri Payet, nine-times champions Marseille won their opening match of the French league season on Sunday, scoring a 3-1 away success at Guingamp.
Pierre-Andre Gignac netted the opener after just two minutes for the 2010 champions with a rebound after an Andre Ayew effort was saved.
Payet doubled the advantage for the 1993 European Cup winners just two minutes later after good work from Ayew down the left before making it 3-0 after just a quarter of an hour.
Malian international striker Mustapha Yatabare pulled one back with 16 minutes remaining after Marseille keeper Steve Mandanda had first saved a penalty from the same player seven minutes after the restart, but Marseille were good value for the three points.
Earlier Sunday, Brazilian striker Brandao struck the only goal to ensure a 1-0 win for Saint Etienne and spoil Fabrizio Ravanelli's debut as Ajaccio coach.
The 44-year-old Italian, who won the Champions League with Juventus in 1996 but has only two years coaching experience at youth level, could only look on as former Marseille marksman Brandao gave the League Cup winners a perfect start to the season.
Crowd trouble before the match between both sets of supporters put a stain on the opening weekend of the season.
Saint-Etienne's team bus was bombarded with missiles from the Corsican club's fans as they arrived at the stadium which led to a series of incidents including supporters from both teams and security personnel.

Defending champions Paris Saint-Germain experienced frustration as they were held to a 1-1 draw at 2012 champions Montpellier in the opening match of the season on Friday.
There was controversy during Valenciennes' 3-0 win at home to Toulouse after referee Stephane Jochem, officiating his first top flight game, awarded a spotkick for what he deemed a foul by Burkina Faso international Steeve Yago on Grégory Pujol only to change his mind several minutes later and red card Serbian Uros Spajic instead.
Jochem said afterwards he would would include the incident in his report to the French League.
