Cautioning the Virat Kohli-led Indian team against underestimating the visiting Australian side in the four-match Test series, former India skipper Sunil Gavaskar told NDTV on Monday that the visitors lack a bit of experience in their pace bowling department. "Australia are a bit short of experience, not class, in their pace bowling department," Gavaskar said. The batting great also said that the upcoming series may not pan out like the one in 2013, which India won 4-0, due to the difference in pitches. "Australia tend to be very dangerous when they are down," he added.
