Spin legend Shane Warne says Australia should not feel disgraced losing to teams like India and South Africa as they played better cricket in the Test series last year.
"There is no disgrace in losing like in 2005, when England were the best team and deserved to win. It's the same. South Africa deserved to win as they were the best side. India have also had enough of losing to Australia and have drawn a line in the sand. Their approach has been: 'Enough is enough, we want to be the No. 1 side in the world'," Warne said.
"I wasn't surprised or shocked," he wrote in his column for the 'Herald Sun'.
Warne said teams like India and South Africa have learnt and improved a lot during Australia's reign at the top while the baggy greens did not usher in new ideas.
"We all have to accept that teams have learned a lot from Australian sides and become better. Plans were put in place and are now starting to pay off. Now it is Australia that needs to have a plan.
"Australia has always been regarded as having the best first-class cricket set-up and has a habit of producing quality players. Well, that structure will now be tested. All aspects of the game must be challenged, issues and roles have to be discussed by Ricky and the selectors, and players identified for the future and encouraged," he said.
The spin great, who retired from international cricket in 2007, had a piece of advice for Australian bowlers whom he described as timid and boring against South Africa.
"After Australia's two losses to South Africa, I reckon our bowlers need to have more imagination and flair. They especially need this when tackling the tail and when the wickets are flat. I have concerns about Australia's ability to take 20 wickets," Warne said.
