"...If we stick too our basics, it is very hard to beat us in India though we didn't win in our last series against England and didn't play to our potential. We have been the No. 1 team in the world, that doesn't come like a dream. We've worked hard," Harbhajan said.
Press Trust of India"These are the same guys who've taken the team to that position. Why I said we could beat them 4-0 is that if we don't believe, who will? I believe that we can do it, then we work towards it. You've got to believe in yourself to make things happen, you work towards it," he said.
Criticised quite often despite over 400 Test wickets in his kitty, Harbhajan said he does not get too affected by it.
"How do I handle, I just keep quiet. Everyone has got their opinion, but unfortunately or fortunately people who have not played to that level, if they say things like I'm not good enough to play for India, it doesn't matter," he said.
"What matters is what my teammates think of me. Those guys are going to be with you, that's what matters. Everyone has got opinions, even I've got my opinion about others, it's not that I'm right all time. You've got to live with it," he added.
Despite the relative inexperience of the visiting Australian team, Harbhajan said the Indians cannot afford to take it lightly.
"Earlier (Australian) teams, when they've come to India, I can see in their batting line up, up to No. 11, all of them were match-winners, experienced players.
"In this team, most of them have played in the IPL, but not in the longer format. The Australians come hard at you, whatever team they might have come with. You've got be there and focus on your job, rather than thinking if they're coming here for the first time," he said.
"The Australian team is always a good team to play against. I'm sure it'll be a good series," he added.
