JAIPUR (AFP) - Former India coach Greg Chappell on Saturday laughed off speculation that he was passing on secret information about the Indian team to Australia. Chappell, who quit as India coach last year after the team's first-round exit at the World Cup, is now touring with the Australian team as their assistant coach. His new role has fuelled speculation that he might be passing on sensitive information to the Aussies, who are training here ahead of the four-Test series beginning on October 9 in Banglaore. "There's nothing called secrets in cricket," Chappell said at a press conference. "Australia and India have played a lot against each other in recent times. The Indians must have footage of Australian players as much as the Australians have for Indians. "There are no secrets whatsoever between the two teams now. I believe the Indian players must also be amused by the talk going around in the last few days," the former Australian skipper said. "Cricket is a game where knowledge is shared. England set up a cricket academy in Australia and they trained under Rod Marsh ahead of an Ashes series." Chappell, who is closely associated with the Rajasthan Cricket Academy, also tried to justify the decision of the team to avail of the academy's top-grade training facilities ahead of the Test series. "The whole idea of coming to India and train in Jaipur was to get acclimatised to conditions, trying to mentally and physically prepare ourselves for the Test matches. "I would not say that India has lost its home advantage just because we've come here to acclimatise, India still has that advantage," he added. Chappell said the Australian team was going through a transitional phase after the retirement of several senior players. "We're rebuilding our team and we have to put the basics together for eventual success," he said. "Test cricket is hard work and nothing more than hard work will make you successful." Chappell also backed captain Ricky Ponting to play a big part in the current series despite having struggled on previous tours. "Ponting's not made many runs in India and he knows about it. He also knows that he has a big role to play and score lots of runs."
