Zamalek have sealed qualification for the CAF Champions League second round with a goalless draw against Chad's Gazelle, compiling a 7-0 aggregate win. The Cairo giants were virtually through following their thumping first-leg win, which marked their biggest-ever continental victory. Saturday's game in N'Djamena saw manager Jorvan Vieira rest some of his key players including top scorer Ahmed Gaafar and star midfielder Ahmed Eid. Goalkeeper Ahmed Al-Shennawi made his competitive debut in the second half, replacing skipper Abdul-Wahed Al-Sayed. Zamalek will face the winner of the match between DR Congo's Vita Club and Dynamic Togolaise, who lost the first leg 3-0.
