Former South Africa fast bowler and bowling coach Allan Donald has labelled the current Proteas attack the best the nation has ever produced, even better than the pace battery he once led with devastating effect the world over.
Led by Dale Steyn and Vernon Philander, rated the top two bowlers in Test cricket, and supported by Morne Morkel, the South Africans have arrived in Australia with an attack sure to test Australia line-up with more than a few question marks.
Alongside former Proteas skipper Shaun Pollock and the likes of Fanie de Villiers and Makhaya Ntini, Donald was once the leader of one of Test cricket's most feared bowling line-ups following their return to the fold in the 1990s.
But the ex-speedster was forced to bow to the current crop, which has helped elevate South Africa to the top of the Test rankings.
"I would have to say that, yes," the Sydney Morning Herald quoted Donald, as saying.
"I'm not just saying that, because I was part of an attack with Shaun Pollock and myself and a few others, and I say that humbly and respectfully, I think this is as good as it gets," he added.
That's ominous news for an Australian batting line-up, which will head to the Gabba for the first Test far from secure.
The opening combination of David Warner and Ed Cowan have yet to convince they are long-term options, while it was less than a year ago that former skipper Ricky Ponting was hanging onto his spot by the barest of threads.
