In 32 previous League matches since 1985, Aces have managed just four victories, suffering 23 defeats in the process.
And in the last 10 outings they have suffered eight defeats and managed just three goals, conceding 17.
The formbook would suggest that thing will not get any better for AmaZayoni, who suffered a 10th League defeat of the season in their last outinhg against Orlando Pirates.
That has left them in 12th place in the standings with 26 points, just four above the relegation play-off place.
By contrast, Sundowns picked up a third successive League win when they beat Chippa United 3-0 last time out.
They are second with 46 points from 23 matches, eight behind leaders Kaizer Chiefs, but with a game in hand.
