Herve Renard has quit as Zambia coach to take charge of Sochaux.
The Frenchman caused one of the biggest CAF Africa Cup of Nations shocks when he guided the Chipolopolo (Copper Bullets) to the 2012 title.
Dismissed as outsiders ahead of the tournament in Gabon and Equatorial Guinea, Zambia defeated star-studded Côte d'Ivoire on penalties after a goalless final.
Hailed as a national hero, Renard was unable to repeat the feat this year, with Zambia making a meek first round exit in defence of the title.
"Herve Renard has been released from the job of Zambia national coach," the Football Association of Zambia (FAZ) said in a statement. "He has been offered a wonderful opportunity at Sochaux. FAZ and Herve have consulted and it has been agreed not to stand in his way.
"It is a compliment for a coach working in Africa to be head-hunted by a European club. It makes us proud to take ownership of Herve's rise."
Renard had two spells as Zambia coach, taking them to the Cup of Nations quarter-finals in 2010 before brief spells in charge of Angola and Algerian club USMA.
He faces a tough task at Sochaux, who crashed 4-1 to Bordeaux on Sunday and are second-bottom of Ligue 1 after nine rounds with just one win.
Patrice Beaumelle, assistant to Renard, will prepare Zambia for a friendly against Brazil on 15 October in Beijing.
