Marseille passed up an opportunity to move two points clear at the Ligue 1 summit as they were held to a 1-1 draw at Rennes.
Jerome Leroy gave the hosts a 37th-minute advantage from the penalty spot but Mamadou Niang secured a share of the spoils for the visitors with an equaliser seven minutes after the interval.
Rennes who made the early running and who almost went ahead in the fourth minute. Carlos Bocanegra's free-kick released Ismael Bangoura, who lobbed goalkeeper Steve Mandanda but was denied by the crossbar.
At the other end, Marseille's first chance of note came just before the half-hour but Edouard Cisse got underneath a Fabrice Abriel corner and headed over the bar.
The deadlock was broken eight minutes before the break, Souleymane Diawara adjudged to have handled in the area and Leroy converting from the spot with a low shot to Mandanda's left.
Niang restored parity in the 52nd minute, though, latching onto a Benoit Cheyrou cross at the far post and making no mistake with a simple tap-in.
Marseille were frustrated in their pursuit of the victory which would have maintained their 100% start to the campaign..
