Marcelo Bielsa tendered his resignation to Marseille president Vincent Labrune, minutes after a 1-0 home defeat by Caen in their first Ligue 1 game of the season.
Bielsa was quoted by the club’s Twitter feed as announcing: “I have just resigned from my job as OM coach … I have completed my work here. I put everything into this job.”
Bielsa has been linked to Mexico's manager vacancy.
“I haven’t spoken with anyone at the Mexican Federation,” he said. “It is only a hypothesis, and I never discuss a hypothesis.”
