Record 11-time title-holders Al Ahly of Egypt and Chabab Belouizdad of Algeria on Friday drew 0-0 for the second time in Group D of the CAF Champions League.
The first goalless stalemate was in Cairo last December and the return match in Algiers, scheduled for the same month, had to be postponed as Ahly were competing in the Club World Cup.
Defending champions Ahly remain top of the table with six points, Belouizdad and Young Africans of Tanzania have five each and Medeama of Ghana four after four rounds, AFP reported.
Each club has one home and one away fixture to come and the group winners and runners-up qualify for the quarter-finals.
Belouizdad full-back Houcine Benayada came closest to breaking the deadlock in the Algerian capital, hitting the post on 50 minutes with a free-kick that took a deflection.
Matchday five will be staged on February 23 and 24 with Ahly and Belouizdad away to Medeama and Young Africans respectively.
