Ireland’s South African-born players are determined to show the locals what they're missing during the three-Test series, says Ireland forwards coach Simon Easterby.
CJ Stander, Richardt Strauss and Quinn Roux are all part of the 31-man travelling party that touched down in Cape Town on Monday ahead of Saturday's first Test.
Stander is expected to start in the back row and Strauss expected to provide back-up for captain Rory Best at hooker.
"They are guys that are very passionate about where they were brought up but hugely passionate about wearing the green jersey"
All three qualified to play for their adopted nation through residency and are likely to get a hostile reception at Newlands - but former Lions flanker Easterby says they are equally keen to prove their worth on home soil.
"CJ's shown with his form over the last three seasons with Munster, he's been outstanding. He's been a real talisman for them," he said. "He's come into our Six Nations squad and done particularly well.
"He plays with his heart on his sleeve and is a real leader. He'll be emotional at the weekend along with Quinn and Richardt.
"They are guys that are very passionate about where they were brought up but hugely passionate about wearing the green jersey.
"To a man that has come through, not just in this week since arriving in South Africa but also the build-up.
"You get a sense that they're very keen to show the country that they were born in what they're missing."
Ireland head coach Joe Schmidt announces his team for the first Test on Thursday.
