Substitutes Florian Thauvin and Valere Germain spared Adil Rami's blushes as Marseille came from behind to snatch a 3-2 victory at Monaco in Ligue 1.
Deservedly leading 1-0 at half-time through Konstantinos Mitroglou's smart header, centre-back Rami gifted the home side two quickfire goals at the start of the second half.
He miscontrolled a pass that sent Radamel Falcao clear. He rounded goalkeeper Yohann Pele but his shot was blocked by Rami, only for the loose ball to fall to Youri Tielemans who fired home.
Rami then failed to deal with a low cross into the area, nudging the ball into the path of Falcao and the Colombia star rifled the ball into the roof of the net.
Former Newcastle United midfielder Thauvin came on to turn the game back in Marseille's favour.
His neat finish made it 2-2 before his corner in stoppage-time picked out fellow substitute Germain and his header crept in.
Rennes made it three league games unbeaten with a 2-0 win at home to Bordeaux, who failed to build on last week's win over Monaco.
New signing Hatem Ben Arfa was introduced to fans before kick-off, with the 31-year-old signing a one-year deal on Saturday.
Benjamin Andre headed Rennes into an 11th-minute lead from Clement Grenier's corner and Ramy Bensebaini doubled their advantage five minutes later with another free header from a corner.
Chances were at a premium after the break, but James Lea Siliki was denied a third by a decent save from Benoit Costil.
In the early afternoon kick-off, St Etienne were held to a goalless draw by Amiens.
Wahbi Khazri forced a decent stop from Regis Gurtner after a superb solo run and was later denied a stunning goal by the assistant referee's flag.
Amiens midfielder Bongani Zungu was taken from the field on a stretcher with what looked to be a knee problem, while Timothee Kolo thought he had won it for the home side but Thomas Leonard referred to VAR and the goal was not given.
