Australian captain Michael Clarke has said that his team still has plenty to do if they want not only to win back the Ashes from England but also to become the world's top Test team, according to reports.
According to Sport24, Australia took a 2-0 lead in the five-Test series following a 218-run trouncing of England in the second Adelaide Test on Monday and are poised to retrieve the Ashes they lost in 2009 should they win the third Test in Perth starting Friday.
The Australians have proved dominant on the usually pacy WACA wicket with victories against England in their last six Tests there and England's only win in Perth came in 1978, the report said.
Captain Clarke urged his players to keep grounded as they look for one more victory to seal the series in the remaining three Tests in Perth, Melbourne and Sydney, the report added.
Australia are currently ranked fifth on the International Cricket Council rankings behind number one South Africa, with England third, and Clarke cautioned against over-expectations in Perth, the report further said.
Clarke described Johnson, who has been man-of-the-match in both Test wins, as having the 'X-factor', according to the report.
He also said Australia's two comprehensive wins had their origins in the last series in England in July-August, which they lost 3-0, the report mentioned.
