He has signed a two-year contract, which is understood to include the option for a further season, as he replaces Antoine Kombouare.

Rosenior was sacked by Chelsea after a little more than three months at Stamford Bridge.

He is taking on his third head coach role in the space of a year as he returns to Ligue 1, with Paris FC looking to build on last season's 11th-place finish after promotion the previous season.

"Liam Rosenior possesses all the qualities we were looking for," sporting director Marco Neppe said.

"He is a modern, demanding coach, renowned for his ability to develop both individual players and the team as a whole. Beyond his tactical skills, we were particularly impressed by his management abilities and his capacity to unite a group around a clear vision.

"I am convinced he has all the qualities to succeed at Paris FC, and I wish him every success in this new chapter of his career."

Rosenior has previously managed in Ligue 1, taking charge of Strasbourg between July 2024 and January 2026, when he left to succeed Enzo Maresca at Chelsea.

With Strasbourg, he finished seventh in the 2024-2025 season, qualifying for the UEFA Conference League with the youngest squad across Europe's top five leagues.

However, his Chelsea team went on a dire run of form, with Rosenior losing 10 of his 23 games in charge in all competitions.

He lost his final five Premier League games, with the team failing to score a single goal, with that form marking the Blues' worst run since 1912.

Paris FC finished the 2025-2026 Ligue 1 season strong thanks to Kombouare, who started in February to help it avoid relegation. It lost just two of its final 11 matches of the season to ensure it retained its top-flight status.

Rosenior's first Ligue 1 match in charge will come against Troyes on 23 August (AEST).
