Michel Der Zakarian has been appointed head coach of Montpellier, the Ligue 1 side confirmed.
Der Zakarian arrives from Ligue 2 outfit Reims as a replacement for Jean-Louis Gasset.
Former Paris Saint-Germain assistant Gasset spent half a season in charge, overseeing a 15th-place finish as Monaco won the title.
Der Zakarian, 54, returns to Montpellier, where he spent 10 years as a player - winning Coupe de France and Coupe de la Ligue.
The Armenian boss is coming off a season at Reims, who were seventh following the 2016-17 campaign in France's second division.
He previously coached Nantes - in two spells - and Clermont.
