Founded in 1901, Rennes represent the Brittany capital and have been in the top flight continuously since 2000. In 2019, they achieved a historic Coupe de France triumph — their first major trophy in 71 years — defeating PSG on penalties in the final.

The Pinault family (Kering Group owners) increased their investment from 2020, funding ambitious transfers and European campaigns. While Champions League and Europa League appearances followed, consistency remains an ongoing challenge.

Rennes are deeply entwined with Breton cultural identity. Brittany flags fill the stands at Roazhon Park (capacity 29,778), and the Celtic-rooted supporter culture gives matchdays a distinctive atmosphere. The "Ruz ha Du" (red and black) colours represent not just the club but regional pride.

The 2025-26 season saw managerial upheaval. Opening coach Habib Beye departed in February, with Franck Haise arriving from Nice. Known for building a disciplined, counter-attacking system at Lens, Haise is tasked with bringing structure and organisation to a talented but inconsistent squad.
