The 18-year-old French midfielder has joined the Bianconeri having made only three league appearances for the Ligue 1 champions.
He made his debut for the club in February 2013, becoming the Parisians’ youngest-ever player in the process.
Coman is described by the official Juve website as “predominantly right-footed, a technical and creative player blessed with extraordinary pace, long-range shooting ability and a unique vision to dictate the game.”
He was born in Paris on June 13 1996 and began his career at the US Senart-Moissy academy before moving to the Parc des Princes in 2004.
The youngster has represented France at every youth level from U-16 to U-21 and he made his Les Bleuets debut in June of last year, scoring in a 6-0 victory over Singapore.
