The Rockets face Durban City at the New Peter Mokaba Stadium on Saturday after securing their final place with victory over Motsepe Foundation Championship side Milford.
The club famously won the lucrative competition by beating Kaizer Chiefs 1-0 in the 2019 showpiece.
Parker unexpectedly finds himself in charge of the side following the sacking of Adnan Beganovic but it up for the challenge.
“I think the universe designed it. It’s by God’s grace,” Parker said on IOL.
“Nobody expected that I would be in this situation – it came as a shock. People expected things otherwise regarding who should be in charge of the Nedbank Cup final.

“Other than that, I am a servant of the game – as a player previously, and now as a coach. A lot of work is done behind the scenes; the club is working together with the coaches and the players.
“The confidence and trust that the chairman has shown in me makes me proud and confident that I have what it takes (to do well). I also have the players’ response.
“So, it’s for all of us to go there and make sure that history repeats itself.”
