Gary Kirsten believes Kagiso Rabada has "got it all" after the South Africa paceman enhanced his reputation by exploiting Australia's vulnerability with the bat.
Rabada claimed a five-wicket haul in the second innings of the first Test at the WACA as the Proteas took a series lead with a 177-run victory.
The hostile quick then claimed 4-34 when Australia were skittled out for 161 in their second innings in Hobart, where the tourists sealed the series with one match to spare courtesy of a crushing win by an innings and 80 runs.
Rabada has taken 41 wickets in 10 Tests since making his debut in the longest form last November and former South Africa coach Kirsten said the 21-year-old has all the tools to be a force on the international stage.
He told Omnisport: "The top managers and coaches in the world always talk about recruiting character and attitude before talent.
"KG has got it all. He has had a fast start to his career and his biggest challenge will be to maintain a level of consistency in his approach and processes, on and off the field."
Much has been made of Australia's Test woes and ex-Proteas captain Kirsten is unsure how long it will take for Steve Smith's side to turn the corner.
Asked if he anticipates a lengthy period of struggle for Australia, he said: "This is difficult for me to answer as I do not have an understanding of their cricketing depth and what players are coming through their system. It would surprise me if they don't.
"Every team will go through cycles where they are suddenly vulnerable in certain components of the game, due either to loss of form or change of personnel.
"Good teams will exploit those vulnerabilities. Quality Test match bowlers will relentlessly examine the fundamentals of a batsmen's technique.
"If batsmen can't answer those questions, they will be exposed. A good succession process will allow for a faster recovery."
