South Africa turn to spin for Australia Test

"Not everything is going to go your way in Test cricket, but you have to be able to find a way to contribute over those five days and I think Imran has done that well for us and I think all of us would love to see him pick up a huge wicket haul.

"Imran is the frontline spinner and we've backed him."

Smith said it was also a great opportunity for Du Plessis, who has played 26 one-day internationals and four Twenty20 internationals for his country.

"I think Faf is in the same mould bowling as JP (Duminy)," Smith said.

"He can play a role and obviously by picking Imran he will front up for the majority of that spin option, but having Faf available is having someone else in the group who can contribute.

"I think he's had a high standard in the last few years. He's played a role in the one-day and Twenty20 formats and I know he's really excited to get the opportunity to play Test cricket."

Smith said the South Africans, particularly the bowlers, were looking to improve after fading in Brisbane after scoring 450 in the first innings.

It will be the second Test match for the Proteas since they attained the number one ranking and expectations are high for a crucial win which could ultimately win the series.

"For us a disappointment in a draw is good for us, it shows that people expect us to play well and to perform well and that's exciting for us," Smith said.

"We come to Adelaide knowing there are a few areas where we can definitely improve on."
