Chauhan said Harbhajan had not uttered anything ‘wrong’ during his altercation with Andrew Symonds and the Australians were raking up such issues only because they cannot accept India's new found aggression.

"Harbhajan has not uttered anything wrong. The Australians are playing mind games. We have got the hearing tomorrow and we will argue our case", Chauhan said.

Asked how Harbhajan had reacted to the whole issue, the former Indian opener said, "He is okay. Such things happen on the ground. We are prepared for the hearing."

On Australian opener Matthew Hayden's assertion that Australia have a strong case, Chauhan said," They will definitely say that. He (Harbhajan) has troubled them the most. They would definitely want him out of the bowling attack."

"We also have a strong case. We will back him," Chauhan told a TV channel.

Chauhan said the Australians were not used to teams retaliating to their sledging and were therefore finding it hard to digest.
