Justin Langer is backing Australia to regain their No1 test mantle in the not-too-distant future, but says it's crucial for the team's star-studded bowling attack to stay healthy.
Australia rose to third in the test rankings after their 5-0 whitewash of England.
Rejuvenated left-arm quick Mitchell Johnson won the man-of-the-series award for his 37 wickets, while Ryan Harris (22 wickets), Peter Siddle (16) and spinner Nathan Lyon (19) were also crucial in the demolition.
The biggest question mark is over the fitness of Harris, who is nursing a degenerative knee injury.
Australia's quest for the No1 ranking will be given a stern challenge when they travel to South Africa for a three-test series next month.
