It was the Chiefs captain's ninth match without conceding, in 14 league games, and speaking after the win, Ben Youssef said that Petersen's form is putting him in contention for Bafana's upcoming Africa Cup of Nations campaign.
The Chiefs captain said on FARPost: "Congratulations to Petersen, congratulations to the goalkeeper coach for a good job he's doing with him.
"The target of Petersen is to go back to Bafana Bafana, to be part of the national team. He's targeting that, and we are following him."
Currently Bafana boss Hugo Broos is prefers Ronwen Williams, Sipho Chaine and Ricardo Goss as his three international stoppers.
Petersen is also seemingly behind Sekhukhune's Renaldo Leaner and AmaZulu goalkeeper Darren Johnson in the Bafana pecking order.
"I think he needs to continue to work to put pressure on the coach of the national team. Why not be part of the squad in AFCON?" added Ben Youssef.
