Announcing Vieira's departure on their official website, New York City were quick to thank the former World Cup victor for his endeavours. "I'm leaving NY with some wonderful memories and I will always be a fan of the club", Vieira wrote in a statement published on Twitter.
Former Arsenal captain Patrick Vieira has been appointed as the new manager of French Ligue 1 side Nice.
Vieira paid tribute to the NYCFC fans that have made his time in NY so memorable.
The ex-Manchester City, Inter Milan and Juventus midfielder was in his third season as head coach of New York City. Our incredibly passionate fans have made this one of the most special experiences I've had in football.
"Though I have enjoyed a wonderful 11 years working alongside my colleague and close friend Pep Guardiola - it has always been my ambition to manage a team again and I really couldn't have hoped for a better opportunity than at this football club", Torrent told the official New York City FC website.
It's that type of institutional knowledge that City Football Group are seeking to build and consolidate across their club teams; call it the globalized version of Liverpool's legendary "boot room" culture but shaped in the belief that best practice can transcend a particular generation of great leaders, or at the very least offset the loss of any particular individual. "After being one of the most revered and successful players in the world, it has been a pleasure for us to watch his transition into coaching". "We know that leaving the club has been a hard decision for him, but we understand his choice to return to Europe where he spent his whole playing career", team vice chairman Marty Edelman said. "We wish him every success in the future and look forward to following his coaching career".
Assistant coach Christian Lattanzio, performance coach Kristian Wilson and physical performance coach Matt Cook are joining Vieira at Nice.
