In the 2014–15 season, Dirar started the opening match of the Ligue 1 season at right-back in a 2–1 loss to Lorient. It came after when new manager Leonardo Jardim began slotting Dirar at right-back position during the pre-season. After missing one match due to an ankle injury, Dirar scored his first goal for the club on 21 September in a 1–0 win over Guingamp. After suffering two separate injuries in November he set up a goal for Lucas Ocampos to score the only goal in a UEFA Champions League match against Bayer Leverkusen, a 1–0 victory on 26 November.
