Manchester City have signed forward Mathys Detourbet from fellow City Football Group club Troyes.
French club Troyes have suspended four players and banned nine fans for throwing flares at each other at the abrupt conclusion of Saturday's game with Valenciennes which left the team on the brink of their second successive relegation to the third tier.
Troyes were relegated into Ligue 2 when they lost 4-0 at Stade Rennais on Sunday.
