Achraf Bencharki scored the only goal that gave Zamalek a 1-0 victory over Raja Casablanca in the first-leg of their Caf Champions League semi-final fixture on Sunday.
Bencharki broke the deadlock at the Stade Mohamed V in the 18th minute with his header off Ahmed Sayed Zizo's cross.
The effort was the Morocco international's seventh goal on his seventh appearance in the Champions League this season.
Despite pressure from the hosts to score an equaliser, Zamalek held on to the precious victory away from home in Casablanca which stretched their unbeaten run across all competitions to seven matches.
