After retiring, Ben Askar started working as a football agent.[2][3] However, he stopped as an agent because he missed being on the pitch and instead started working toward his coaching license.
Ben Askar started his coaching career with the U17 team of Stade Mayennais.[1] In mid-2015, Ben Askar also began working for UNFP FC (Union Nationale des Footballeurs)[4][5] as well as being appointed manager of AS Bourny Laval, which also was a part of the process to get his license.[6] In May 2016 he announced that he would not continue at Bourny because he wanted to try something new with more adrenaline.[7] Ben Askar also left UNFP in 2017.
In the summer 2018, Ben Askar had several offers but preferred to stay in France. He was then appointed manager of AC Ajaccio's U19 team.[4] In November 2019, he was appointed manager of his former club, Umm Salal SC, in Qatar.[8]
In April 2024 Ben Askar was appointed manager of Moroccan side Wydad AC.[9]
