New York City FC manager Patrick Vieira has left his position to join French Ligue 1 club OGC Nice, both teams said.
Vieira, who took charge of the American Major League Soccer club in 2016, will replace Lucien Favre at Nice, who finished eighth in the French league last season.
"Leaving New York is an incredibly difficult decision for me and for my family and one that has not been taken lightly," the 41-year-old told NYCFC`s website.
"Having the opportunity to be a Head Coach in New York is something many dream of. Our incredibly passionate fans have made this one of the most special experiences I`ve had in football."
Vieira, a World Cup winner with France in 1998, began his coaching career with Manchester City`s youth team before joining New York and guiding them to successive playoff appearances.
Assistant coach Christian Lattanzio, performance coach Kristian Wilson and physical performance coach Matt Cook will follow Vieira to Nice.
