While Sundowns were dominant in terms of possession throughout the full 90 minutes, Al Ahly were able to clinch the win as they focused on playing on the counter attack.
Taher Mohamed Taher broke the deadlock in the 23rd minute, before Salah Mohsen doubled the scoring after taking advantage of Sundowns keeper Denis Onyango’s howler.
Mohsen, who hasn’t been in great form this season, has managed to score in another crucial game for the Reds after scoring in their 1-1 draw against Zamalek in the Cairo Derby last week.
The 22-year-old talked about his form and the possibility of reaching the CAF Champions League semi-finals.
“The past period we were going through a lot of pressure due to our schedule and that affected the players, but no one spared the effort during the Sundowns match and we managed to win,” Mohsen told Al Ahly TV.
“The rematch in South Africa will be very difficult but we can qualify from there.
“Football means diligence, and I’ve been striving lately. It’s not important to score goals, but the most important thing is for the team to achieve victory and the desired goal.
“Our goal now is for the players recover well, to get rid of fatigue, before traveling to South Africa.
“Mosimane asked me to focus and help the team when going forward, and also support of Ayman Ashraf defensively,” he concluded.
Al Ahly will face Sundowns in the second-leg on May 22 at the Lucas Masterpieces Moripe Stadium, in Pretoria and they are expected to remain two days after the game before traveling to Qatar to face RS Berkane in the CAF Super Cup.
