Pitso Mosimane's Al Ahly secured a narrow 1-0 in over Al Mokawloon in the Egyptian Premier League match on Sunday night.
The only goal of the encounter was netted by Amr Al Salaya a few minutes before half-time break and it was enough to hand Mosimane a winning start in Egypt.
Mosimane, who resigned as Mamelodi Sundowns head coach on Wednesday, was hoping to start his tenure at the Red Devils with a victory after replacing Rene Weiler on Thursday.
The accomplished tactician recalled club captain Mohamed El Shenawy to the starting line-up after he was rested by Weiler in the midweek clash against Tersana.
