Over the years, the Australian cricketers had been known for their aggression and dominance on the field. Sledging was an integral part of their game and mentally breaking down opponents even before the battle begins on the field was a common phenomenon down under.However, a lot has changed with Australian cricket since the infamous ball-tampering scandal that shook the cricket fraternity earlier this year. Two of Australia’s best batsmen were handed a one-year bans for their involvement in the controversy that severely hampered the image of the world champions, who had been taken pride in the way they’ve played their cricket.Australia have been forced to tone down their verbal aggression so much so that several cricketers, including South Africa captain Faf du Plessis, urged the Aussies to not lose their originality.Even as Australian cricket is going through a crisis period, Virat Kohli’s Team India have arrived Down Under, hoping for an unprecedented Test series win. In fact, the visitors are considered favourites, given the hosts are without two of their wreckers-in-chief.Also read: Shikhar Dhawan revels in massive Indian turnout at SCG: Guess they love me a lotHowever, former Australia captain Ian Chappell has warned Kohli’s touring team not to underestimate Australia, especially their bowling attack. The 75-year-old believes short-pitched deliveries will be the new verbal volleys of Australia in the much-anticipated Test series.Also, the Australian pace attack, consisting of senior pros Mitchell Starc, Josh Hazlewood, Pat Cummins, and Peter Siddle, will be more than willing to shoulder the extra burden, according to Chappell.advertisement”With Australia looking to temper their on-field behaviour after the ball-tampering debacle, the Indians had better believe that while this may result in a reduction in verbals, there will be no let-up on the short-pitched deliveries,” Chappell wrote in his column for ESPNCricinfo.Also read: India extend unbeaten streak in T20 Internationals to 10 series after SCG winHe added: “Australia should not be underestimated: they have a top-class attack, headed by three excellent fast bowlers in Mitchell Starc, Josh Hazlewood and Patrick Cummins. As a result of three suspensions, Australia will field a depleted batting line-up, which means their bowlers will be even more determined to limit the opposition’s scoring.””Therefore the Indian top three should be aware that the Australian pacemen will be seeking early wickets in order to get the redoubtable Virat Kohli in while the ball is still shiny.”Also read: Took me a while to back myself after going for 55 runs in Brisbane: Krunal PandyaMeanwhile, Chappell also stressed the need for the bowlers to find the right lengths once the red cherry loses its shine and stops moving in the air.A lot is being said about the quality of India’s pace bowlers, who found a lot of success in South Africa and England earlier this year. However, they need to adapt to the Australian conditions and hit the right line and lengths in order to be as successful as they were in the earlier tours.”The other objective to be finalised is the right length for the faster bowlers to claim victims in Australia,” Chappell added.”In England the Indian fast bowlers had great success bowling on a fuller length to take advantage of the swing and seam on offer. That will work in Australia while there’s some movement through the air or off the pitch, but when that disappears, the trick is to find a length that will still create opportunities.”India will play a four-day warm-up match against Cricket Australia XI in Sydney from November 28 before heading to Adelaide for the first of the four-match Test series, starting December 6.
