WAC on Saturday ended their 25 year wait for a continental trophy when they edged Al Ahly 1-0
Walid El Karty scored the only goal on 69 minutes to give the home team a 2-1 aggregate triumph after they forced a 1-1 draw in the Egyptian city of Alexandria last weekend.
Achraf Bencharki, who equalised in the first leg, set up the goal with a deflected cross for El Karty to score his third goal of the competition.
The victory bridged a 25-year gap for Wydad, who conquered Africa for the first time in 1992 when they defeated Al Hilal of Sudan.
Wydad pocketed a record $2.5 million and are guaranteed at least another $1 million by competing at the Fifa Club World Cup in the United Arab Emirates during December.
