POTCHEFSTROOM, South Africa (Reuters) - Australia captain Michael Clarke has laid down the challenge to South Africa's bowlers to prove they are the world's best attack after suggesting on Friday his side owned that honour ahead of their three-match test series starting on February 12.
The fast-bowling trio of Dale Steyn, Vernon Philander and Morne Morkel have played a leading role in catapulting South Africa to the number one test ranking, but following their recent Ashes series whitewash of England, Clarke believes Australia's attack is even better.
