Guingamp's manager in May 2010. On 3 May 2014, he led Guingamp to success in the
Coupe de France for only their second time by beating his old club
Rennes. On 8 November 2018, Gourvennec returned to Guingamp as their new manager after sacking
Antoine Kombouaré. On 22 May 2019, the club announced that he had left the club by mutual agreement, after Gourvenenc was unable to guide the team to safety and the season ended with relegation to Ligue 2 for the first time since the 2003–04 season. On 5 July 2021, he became the new manager of a
Lille side fresh off winning the
2020–21 Ligue 1 title, following the departure of previous manager
Christophe Galtier for
Nice. On 1 August 2021, he won his first trophy with the club after defeating
PSG 1–0 in the
2021 Trophée des Champions. He was dismissed on 18 March 2024, and replaced by Antoine Kombouaré. On 11 August 2025, he was named the head coach of
