Youssef Obama scored a stoppage-time equaliser for Zamalek in a 1-1 draw against Angolan giants Petro de Luanda at Borg El Arab Stadium in Alexandria on Sunday evening.
The result leaves the White Knights bottom of Group D, having accumulated but two points from three matches, as pressure continues to mount on head coach Christian Gross despite the club's dominance in the Egyptian Premier League.
Petro sit on four points, level with NA Hussein Dey while Kenyan champions Gor Mahia lead the way on six points following their win over Hussein Dey in Nairobi earlier today.
Toni teed up fellow Brazilian Tiago Azulao on the hour mark as Os Tricolores opened the scoring in Egypt, only for Obama to level matters in the fourth minute of referee's added time.
Petro host Zamalek in Luanda in the reverse fixture on the 3rd of March.
