Ajaccio coach Albert Emon has backed Marseille to pick themselves up from their goalless draw on Friday and fight for the Ligue 1 title.
Elie Baup's side are currently six points behind league leaders Paris Saint-Germain in third place.
"I think they can pick themselves up," Emon told reporters. "That sort of bad display can help them do better in the future.
"You have to turn the page quickly in football. I know that OM will wake up soon to finish in the European qualifying places."
Ajaccio are 13th in the standings with 33 points from 29 matches.
