"It is a big boost to win 4-0 with this unit. Credit goes to every one. The last one and a half years has not been great for us in Tests, but they showed a lot of character, put in good performance and battled it out," Dhoni said at the post match presentation ceremony.
"You need to battle it out and that was the case in this series," he added.
India, however, got their act together to complete a historic 4-0 clean sweep against Australia by recording an emphatic six-wicket victory in the fourth and final cricket Test here, and Dhoni felt it was an important series from the team's point of view.
"I think it was an important series for us, there were a few changes in the side. It was up to the individuals to rise up and do well. I think they all did it, everybody performed."

"Almost all the pitches were turning, and on all the wickets we batted second, which meant we had to face the (Aussie) bowlers in the fourth innings, we all know how difficult that is," said Dhoni.
He said the Kotla wicket was slightly better today as compared to yesterday.
"This wicket I thought it got slightly better ... I may be wrong, but I thought yesterday was harder to bat on. The new ball did not turn as much," he said.
