FC Lorient capitalised on an early numerical advantage to overwhelm Stade Rennais 4–0 in a Breton derby on Sunday, securing their first victory since returning to Ligue 1. Rennes were reduced to nine men inside 11 minutes when debutant midfielder Mahdi Camara was dismissed for a high challenge and defender Christopher Wooh followed for a last-man foul, forcing coach Habib Beye’s side to play 80 minutes short-handed. Lorient eventually broke through in first-half stoppage time as Sambou Soumano dribbled past two defenders to score. The hosts pulled away after the interval, with Aiyegun Tosin heading in a corner seconds after the restart before substitutes Pablo Pagis and Théo Le Bris added goals in the 64th and 68th minutes. The rout leaves Rennes winless after two matches and already counting three red cards this season, while Lorient become the first of the newly promoted clubs to claim three points.
