Grimandi, 48, will rejoin ex-Gunners teammate Patrick Vieira who is the Ligue 1 outfit’s coach, after the pair played together for five seasons in north London.
The Frenchman’s arrival at the Allianz Riviera will comfort Vieira after the pair responsible for bringing him to the French south coast, Jean-Pierre Rivere and Julien Fournier left their roles in January due to a disagreement with the club’s Chinese-American majority owners.
Vieira has a release clause in his contract as boss which allows him to leave his position if the club’s executive board changes.
After spending 13 years with the English outfit Grimandi will oversee the first team, the academy and recruitment at Nice, who sit in seventh place in Ligue 1.
