During a 2–1 victory against Lokeren on 21 February 2011, Dirar was involved an incident with teammate Ivan Perišić over who should take a free-kick; Perišić took the kick and scored, though Dirar refused to celebrate. He was sent to the reserve team for the third time that season after a 4–1 win over Kortrijk on 12 March when he again was involved in an incident with a teammate over who should take a free-kick, this time with Vadis Odjidja-Ofoe. After the incident, Club Brugge supporters booed him, leading him to respond to the supporters with an obscene gestures. He was ordered by manager Koster to leave the pitch to avoid aggravating the situation. After the match, Dirar apologized to the club and Odjidja-Ofoe during a press conference, saying his behaviour was unacceptable.
