In the opening game of the 2014–15 season, Makoun made his first appearance, starting and playing 63 minutes before being substituted, in a 2–0 loss against Olympique Lyonnais. However, this turns out to be his only appearance for the side, as he was dropped from the first team, due to his poor relationship with Manager Philippe Montanier. As a result, the club was keen on selling him but the move was never materialised. Because Makoun stayed at the club, he spent most of the 2014–15 season, training with the first team and playing in the reserve match. At the end of the 2014–15 season, Makoun was released by the club.
