The experienced centre-back believes South Africa's defensive future is secure after the duo emerged among the tournament's standout young defenders.
Okon and Mbokazi formed a solid partnership at the heart of Bafana's defence, playing in all four matches and helping Hugo Broos' side reach the knockout stages for the first time.
“I love it, shout out to Ime, TLB (Mbokazi) knows, and you can see where our future is going,” Kekana said, as reported by Sowetan.
"This is what we love to see.
"It might have been us before or whatever, but we want the second or third generation to do even better and set the bar.
“That was the world stage; those are two young boys with massive futures.
"One can only wish them the best, and we say keep it up, keep it going.”
