Springboks captain Siya Kolisi said he hoped his side's Rugby Championship triumph would provide fresh inspiration to South Africa as a whole following the world champion's thrilling 29-27 win over Argentina at Twickenham on Saturday.

"I think I've worn this jersey when nobody wanted to watch us play and when it was hard to get a win," Kolisi, who previously skippered South Africa to back-to-back world titles in 2019 and 2023, told reporters.

"And now, at this moment, no matter how tough it is in the game, we know how to win, we know how to fight, we know how to dig deep."
