The West Africans overcame the challenge of Bafana Bafana in the quarter-final of the 2019 Africa Cup of Nations to seal their progress to the semi-final
Samuel Chukwueze broke the deadlock in the 27th minute but Bongani Zungu’s header in the 71st minute, after a VAR review, drew the teams level.
The game was heading to extra-time until William Troost-Ekong pounced on a defensive error from goalkeeper Ronwen Williams to secure Nigeria’s progress.
The triumph at the Cairo International Stadium means the Super Eagles have qualified in nine of their 10 quarter-final appearances at the Afcon finals, but Rohr has reserved praise for Stuart Baxter’s men as he looks forward to 'more difficult' fixture in the last four.
“It was a great match. South Africa is a very good team, they had a very good game against Egypt but it's too difficult to do this two times in a row,” Rohr said after the game.
“We were lucky to score in the last minute, but yet we were mentally strong to do this. I salute South Africa for having a great team.
“What was the best today is the great spirit between both teams. Our next game is going to be more difficult, but we will be ready.”
