Former Arsenal captain Patrick Vieira has been appointed as the new manager of French Ligue 1 side Nice.
"Leaving New York is an incredibly difficult decision for me and my family and one that has not been taken lightly," said Vieira.
Nice finished eighth in Ligue 1 last season, missing out on a Europa League place by one point.
Vieira takes over from Lucien Favre, who was appointed Borussia Dortmund Coach in May 2018
Assistant coach Christian Lattanzio, performance coach Kristian Wilson and physical performance coach Matt Cook have also left New York to join Vieira at Nice.
During his playing career, Vieira won four FA Cups and eight league titles.
He won six major honours at Arsenal between 1996-2005 before helping Juventus finish top of Serie A in 2006, although they were later stripped of the title
However, he then helped Inter Milan win four straight Italian titles from 2007-2010 before joining Manchester City in January 2010, helping them win the 2011 FA Cup.
His 107 caps for France include winning the 1998 World Cup and Euro 2000.
Vieira began his coaching career in impressive fashion, guiding New York to back-to-back play-off appearances in his first two seasons.
He leaves with New York in second place in the MLS' Eastern Conference after winning eight of their 15 games.
