Ernst Middendorp's charges got the better of Orlando Pirates on penalties to advance to the Telkom Knockout semi-finals on Saturday afternoon.
Despite failing to score from the spot against Cape Town City in the last 16, Manyama confidently stepped up and dispatched his spot-kick as Chiefs won 4-2.
"Obviously the last time I missed, but look I'm a big boy, I know I will miss sometimes but I was very calm, actually mine came after they had missed, it was very vital, mentally you gotta be strong. Even when they said, "Are you taking?", I said, "Ja I'm taking it", I've been taking at training the whole week and I didn't worry I missed before, you learn from this kind of things, I knew I had to do better and I'm glad I did better," he said.
On the actual game, Manyama was surprised that the Buccaneers did not pair Gabadinho Mhango with Tshegofatso Mabasa from the start.
"We knew we were gonna meet a different Pirates, this game is special as you know in the country, but I gotta give credit firstly to our fans they've been with us since the beginning of the season, they've been selling out stadiums, so ja this is for them.
"Secondly to the boys, 1-0 down against Pirates, maybe you can say luck when they get a red-card we raise it, we never stop fighting, we fight week in, week out you know and we take it from here, we have a game against them next week, so ja so far so good," he continued.
"When you play Pirates you don't know which formation you gonna face, we had hoped they gonna start with Mhango and Mabasa but now they came completely different, so we had to switch it up a bit.
"First half we were a bit lost, then second half, obviously when 'Dumi' [Dumisani Zuma] comes in, I gotta praise him also, he raises the whole team with his energy and how he plays you know, so we take a win even though Pirates deserved it too. I mean to fight the way they did with ten men you gotta them huge respect also."
