This fixture has served up goals in the past and did not disappoint once again.
The opening goal involved a bit of luck on the part of Sundowns as a scramble from a Tebogo Langerman cross saw the ball fall kindly for Themba Zwane, who slotted home in the 32nd minute.
Tembo opted to start with the bulldozing Thamsanqa Gabuza on the bench but later brought him on to inject power upfront.
Gabuza's introduction, in the place of defender Luke Fleurs in the 50th minute, contributed to the equaliser in some way as he spread the Downs backline.
This allowed Kudakwashe Mahachi to go on a dazzling run to earn a penalty after he was fouled by Andile Jali. Skipper Dean Furman stepped up to convert the spot kick in the 54th minute.
It was not long before Sundowns got their lead back when Morena scored the winner. Downs continue to apply pressure on Chiefs with some 12 games to go.
