South Africa vice-captain Adriaan Strauss has "no doubt" 20-year-old Johan Goosen will succeed in his first Test start.
Goosen has been selected by Springboks head coach Heyneke Meyer to start at fly-half in Saturday's Rugby Championship clash against Australia ahead of regular number 10 Morne Steyn.
Strauss, who is Goosen's club captain at the Cheetahs, said: "I've told him before he handles pressure better than any other player I've met. So I have no doubt he is the kind of player who can handle it."
He continued: "Sometimes it looks like he doesn't feel the pressures at all.
"He will probably have some nerves but he won't allow it to get the better of him.
"You see the best of Johan under pressure."
Steyn has received plenty of criticism during his team's opening four matches of the Rugby Championship.
Meyer has claimed the 28-year-old needs a break and believes the Springboks will lose very little with Goosen in the team, while Elton Jantjies will be on the bench to provide cover.
"Morne, in the last four seasons, has played close to 140 matches at Test, Super Rugby and Currie Cup level and probably deserves a break," Meyer said.
"But this also provides a great opportunity for Johan, a player I rate very highly. Morne is a quality player and a fighter and I know he will bounce back."
