Kaizer Chiefs on Sunday defeated former boss Steve Komphela when both sides met for the Macufe cup competition.
This win has motivated the players with big games coming up from the TKO game to the Soweto derby slated for the 27th of this month.
Komphela who won the trophy back to back at Chiefs tasted defeat in a 2-0 loss to his former employers with Giovanni Solinas unleashing his available arsenal.
Manyama had a big chance to put Chiefs ahead after going through on the left side of the box, but his effort could not find the target.
Both coaches were using the encounter to field some of their fringe players along with the regulars, although that did not affect the flow of the game.
Manyama finally found the breakthrough for the Glamour Boys in the 36th minute with a sweet left-footed shot from the left side of the box that sailed into the bottom left corner of the keeper.
Jacky Motshegwa looked to restore parity for Siwelele five minutes before the break with a stinging strike from outside the box, but Amakhosi goalkeeper Bruce Bvuma made a double save to preserve the lead for the visitors heading into the break.
Manyama was certainly Chiefs’ liveliest player on the park, but he should have doubled the lead after 50 minutes as he volleyed over the crossbar from inside the box.
Solinas made a couple changes after the hour as Bernard Parker and Dumisani Zuma were introduced for Paez and Jayiya.
Zuma was unlucky not to have made it 2-0 for Chiefs with a quarter of an hour remaining after lobbing Siwelele goalkeeper Sipho Chaine, but his effort was cleared off the line.
Bongani Sam should have equalised for Celtic four minutes before time after going through inside the box having space but he guided his low side-footed shot slightly wide.
Zuma sealed the result in stoppage time for Chiefs, netting into an empty net after a brilliant square pass from Parker, 0-2.
