Jordan Ayew was on target on Sunday when Marseille's winning run in Ligue 1 season came to an end in a 4-1 defeat at mid-table Valenciennes.
The 20-year-old scored the consolation for Marseille who had won their opening six matches.
Jordan had replaced his elder brother Andre in the 64th minute.
A double by much-travelled striker Anthony Le Taellec and one apiece from Foued Kadir - gifted to him by Marseille goalkeeper Steve Mandanda - and a brilliant opener by Gael Danic gave Valenciennes the points.
