In the 2015–16 season, Dirar started in all seven matches, both in the Pro League and UEFA Europa League qualifying stages. However, in late August, he suffered ankle injury which kept him sidelined for several weeks. After four weeks out with an injury, he made his return to the first team on 24 September 2015, where he set up one of his side's goals in a 3–2 win over Montpellier, followed up by scoring his first goal of the season in a 3–3 draw against Guingamp. However, he continued to remain sidelined, including suffering another ankle injury.
