Trailing by 0-2, Clarke warned India of a possible turnaround in the last two matches in Mohali (Mar 14-18) and Delhi (Mar 22-26).
"It is not in our nature to give up without a fight. We have every chance of making a comeback and levelling the series 2-2. We feel if we win one we can win two," an optimistic Clarke said about his team's chances.
"We have to win the next two Tests to level the series and that is our main focus. But obviously it is going to be tough as India are playing really good cricket at the moment."
And the Australian skipper was modest in admitting that India were by far the better side on display in the opening two Tests.
"No excuses for the defeats. We were outplayed in all facets of the game -- batting, bowling and fielding. The credit must go to India. But we need to improve as team," Clarke said during a function announcing Spartan Sports Goods' association with capital's Hyatt Regency hotel.
