Moroccan striker El Kaabi, in the 71st minute, scored the only goal of the match and gave Casablanca the first win, who had yet to win a game in this year's African Champions League.
Wydad and Horoya share the leadership of Group C, with three points, followed by Petro and the Kaiser Chiefs, both with zero, although the South Africans have not yet played any games.
Also noteworthy for Al-Ahly, from Egypt, current holder of the trophy, who was surprised in Tanzania by Simba (1-0), in a match also of the second round, but in Group A.
