Zungu sealed South Africa's 2-0 win over Sao Tome and Principe at Moses Mabhida Stadium with a headed goal after coming off the bench in the second half.
Before the clash there was a lot of talk about Ntseki and Zungu's relationship after the Rangers star finally got a national team call-up since Ntseki took over from Stuart Baxter.
But after 'Ben 10' produced a masterclass substitute's performance and scored, he went over to Ntseki to give him a heartwarming handshake, which was well appreciated.
Ntseki said after the match that the handshake was a symbol of respect and appreciation for each other.
"I think that symbol of shaking our hands like that, it was out of respect for one another because when I shake hands, when I thank everybody, that is a respect I give," Ntseki said.
"I think it was fitting for him to say thank you and for me to say, 'Thank you, you came in from the bench, you scored the goal, you came in with the right attitude and you had a very good game.'
Ntseki continued: "Like I said, you get rewarded if the attitude is right, confidence is right and if the faith towards your teammates and technical team is right.
"I think if you say much about the thank you handshake, it was actually saying to the public out there, there's never been issues with players because they are the one to make me a good coach and I'm the one to make them better players.
"So it a two-way traffic. The respect we have for each other as South Africans is important."
Zungu is expected to start in the second leg at Nelson Mandela Bay Stadium this afternoon (15h00) as Bafana look to finish off the job and get one step closer to confirming their spot at the next Africa Cup of Nations.
