After beginning his professional career in his native Algeria with Paradou AC, Atai was sent on loan to Belgian club KV Kortrijk in 2017. Despite a season in which he suffered a myriad of injuries, Kortrijk nevertheless decided to exercise the purchase option in the loan.[3] Atal joined French club Nice from Kortrijk in 2018, and started the opening match of the season.[4] He scored his first goal for his new side in November, recorded a hat-trick in April, and ended his first season with six total goals.[4][5] He underwent surgery in December 2019 to repair a torn meniscus.[6][7]
On 14 October 2023, amidst the 2023 Israel–Hamas war, Atal posted a video on social media of Palestinian preacher Mahmoud al-Hasanat asking God to "send Jewish people a dark day". He quickly removed the video after receiving criticism, notably from Nice mayor Christian Estrosi, who stated that unless Atal "denounces Hamas terrorists, he no longer has a place at [OGC Nice]".[12] Atal subsequently published a message on Instagram apologizing for posting the video, and clarified his beliefs by stating that he "denounce[s] all forms of violence".[12] On 16 October, the Nice public prosecutor's office initiated a preliminary investigation into Atal on charges of "defending terrorism".[13] Two days later, OGC Nice suspended Atal until further notice after the anti-Semitic post.[14] On 25 October, he was suspended for seven matches by the Ligue de Football Professionnel for posting the message.[15]
