Pays de Cassel

US Pays de Cassel was founded in 2018 after the merger of four smaller local clubs: Hardifort, Noordpenne-Zuytpeene, Bavinchove-Cassel and Arnèke.

On 14 January 2023, Pays de Cassel eliminated Championnat National 2 (fourth-tier) side Wasquehal in the round of 64 of the 2022–23 Coupe de France following a penalty shoot-out. This set up an encounter with Ligue 1 champions Paris Saint-Germain in the following round, played at the Stade Bollaert-Delelis in Lens as Pays de Cassel's stadium did not meet the criteria to hold the game. At the time, Pays de Cassel had an annual budget of €150,000 while PSG's was €800 million; the two clubs were worth €400,000 and €3.2 billion, respectively. PSG won 7–0, with five goals from Kylian Mbappé.
