Manchester City has completed the signing of 19-year-old French winger Mathys Detourbet from Troyes in a deal worth approximately €25 million ($29 million) including performance-related add-ons. The transfer, announced on June 27, 2026, marks a notable first: Detourbet becomes the inaugural Troyes academy product to make an internal move to Manchester City within the City Football Group network.
The deal and what’s behind it
Detourbet, born on April 29, 2007, has been part of the Troyes system since the age of eight. The young winger played a pivotal role in Troyes’ promotion to Ligue 1 during the 2025-26 season, with initial reports of a transfer agreement surfacing back in mid-May 2026.
Detourbet isn’t heading straight into Pep Guardiola’s first-team plans. He’s expected to be loaned to AS Monaco for the 2026-27 season, giving him top-flight experience in France before eventually integrating into Manchester City’s squad.
Both Manchester City and Troyes sit under the City Football Group umbrella, which makes this transfer structurally different from a typical open-market acquisition. Until now, that pipeline hadn’t produced a direct Troyes-to-Manchester City transfer. Detourbet changes that.
