Manchester City have signed Mathys Detourbet from Troyes, the French club have announced.

The 19-year-old has completed a reported €25m (£21.6m) to the Etihad Stadium, with both teams part of the City Football Group.

The forward scored three goals and provided five assists for Troyes in Ligue 2 in 2025-26 as they earned promotion back to the top-flight as champions of the second division.

In the league, Detourbet completed more dribbles than any of his team-mates (44), while he directly contributed to the joint-third most goals (eight).

Detourbet, who joined Troyes' youth setup at the age of eight, is reportedly set to spend the 2026-27 season on loan with Monaco.

"Troyes is particularly proud to have supported Mathys' growth both as a player and as a man," said the club.

"The whole club warmly thanks him for his commitment and professionalism."
