Sundowns had eliminated record 12-time champions Al Ahly at the semi-final stage on away goals while Pyramids saw off Sundowns’ provincial rivals Orlando Pirates 3-2 on aggregate.
In an entertaining opening 45 minutes played out in beautiful weather, Sundowns had more possession but it was the visitors who carved out three clear-cut chances.
However, Fiston Mayele, the competition’s joint-top scorer this season, sent the first two off target and was flagged offside for the third as he again failed to test Williams.
The composure of Pyramids eventually began to wane in the second half as they could be seen retreating, struggling to maintain sustained possession and barely causing issues for Sundowns.
Ahmed Atef was awarded a yellow card for time-wasting as early as the 48th minute as Krunoslav Jurcic’s side looked content to try and play for a draw.
Ribeiro eventually broke the deadlock but Sundowns could not add to their lead and, despite playing in a sea of yellow with virtually none of their own fans in attendance, Pyramids front man El Karti provided a late twist.
Sundowns are the dominant force in South African football, recently wrapping up a record-extending eighth consecutive domestic title, and will have to negotiate a potentially difficult second leg.
Although Pyramids do not boast the level of support enjoyed by Cairo rivals Al Ahly and Zamalek, Juric’s men will hope to capitalise upon hot evening conditions in North Africa and take a step towards establishing themselves as a giant of the continental game.
