Virat Kohli was the captain of Mitchell Starc in Royal Challengers Bangalore (RCB).
"Obviously, he's a fantastic player. The way India play this series and go about their cricket, it's up to them," he added.
Earlier, Team India head coach Ravi Shastri defended Kohli's antics in the Perth Test. "What's wrong with his behaviour? As far as we are concerned, he is an absolute gentleman," Shastri had said.
Former Australian skipper Mitchell Johnson, on the other hand, slammed Kohli for his behavior terming it disrespectful and silly. "At the end of the match, you should be able to look each other in the eyes, shake hands and say 'great contest'," Johnson wrote in a column for Fox Sports.
"Virat Kohli could not do that with Tim Paine, shaking the Australian captain's hand but barely making eye contact with him. To me, that is disrespectful.
"Kohli gets away with more than most cricketers simply because he is Virat Kohli and he gets placed on a pedestal but this Test left the Indian captain looking silly," he added.
The ongoing Test series between India and Australia is currently level at 1-1.
The third match of the Test series will be played in Melbourne from December 26.
