The Springboks captain was asked what song he was going to sing to celebrate the victory.
Rather than answering the question, Kolisi simply burst into song.
The 35-year-old launched into a Gwijo, with supporters on social media identifying the song as “Kubo”, as the celebrations continued around him.
The spontaneous moment immediately went down well with fans.
One wrote: “Siya Kolisi. Remember that name.”
Another posted: “Siyamthanda Kolisi is literally the best captain ever man.”
A Welsh supporter added: “I’d run through a brick wall for Siya Kolisi. What a player, what a leader and what a bloke.”
Another simply said: “Siyamthanda Kolisi. What a leader, man!”
Singing has long been an important part of Kolisi and the Springboks’ team culture, with the captain regularly leading Gwijo songs before and after matches.
This time, he didn't even need to be asked twice.
