The 30-year-old, who was released by the Glamour Boys in April 2017, scored the final goal in Chippa's 3-0 win at FNB Stadium over the weekend.
The match was marred by crowd trouble as Chiefs fans vented their frustration at Steve Komphela and his charges, who slipped 10 points behind log leaders Mamelodi Sundowns with four games left for the Soweto giants.
The Chilli Boys rose to seventh spot in the Absa Premiership standings with the victory.
"It was so overwhelming scoring against my former team," Manqele tells KickOff.com. "At least I managed to get onto the score sheet. After the second goal I begged the coach to put me in. He said, 'Okay go and warm up'.
"I was not happy with the way Chiefs played at the back, that's where I told myself that if I can get in here I will definitely score today. There were spaces everywhere in their defence. Defenders were not covering for each other, they were not tight at the back. Even their energy was not there. It was a great win for us because even now if you can check we are in the top eight, although there is still a long way to go."
Manqele maintains he was not looking to prove a point against his ex-employers.
"I just wanted to score and it happened. I haven't been playing that much so I was happy for this goal. Chiefs is a big team and Steve is a good coach, pity things are not going well. Chiefs is a big team so obviously the supporters expect wins but things will be right for him. These things happen in football they just have to be patient."
