Soulymane Diawara has said that he is "disgusted" at how Marseille succumbed to a 1-0 defeat at home to Nancy on Sunday.
The defeat saw Les Phoceens fall six points behind leaders Paris Saint-Germain in the race for the Ligue 1 title, but the Senegalese centre-back is still confident of catching their fierce rivals.
"There is no crisis," Ligue1.com quotes Diawara as saying. "Naturally, after a defeat, you're never in high spirits. And to lose like that... I'm disgusted, because I know we can do a lot better.
"Still, we remain in third place and we're lucky enough not to be too far off the two top teams.
"I know that we can still catch Paris and Lyon. I'm sure of what I'm saying."
