Ireland's South African-born loose forward CJ Stander has responded to a suggestion by Rassie Erasmus that the Irish forwards were "soft".
Erasmus, who coached the Springboks to World Cup glory in Japan last year, made the claim in a behind-the-scenes Chasing the Sun documentary on South Africa's campaign.
While addressing reporters ahead of Ireland's Autumn Nations Cup clash against England at Twickenham this week, Stander was asked what he thought of Erasmus' comments.
"It's a bit of a challenge. If that is his view and that is what he believes, I would like to, not really prove him wrong, but I'd like to show him what we can do and what we have done before," Stander said.
In the documentary, Erasmus described Wales, who were South Africa's semi-final opponents, as "tough fu***rs who are not softies" and that "they're not Ireland or England who goes away".
Stander continued: "That is a big statement to make. He put it out there so, you know, that's his prerogative.
"If that's what he thought of us, it is not going to be easy to change his view. Luckily, we are not playing against them this week. We will get them at some stage."
Erasmus and Stander worked together while the former was director of rugby at Irish province Munster in 2016-17.
Stander will start at No 6 for Ireland in Saturday's clash at Twickenham.
Kick-off is at 17:00 (SA time).
