Indian captain MS Dhoni praised his team for a 4-0 series whitewash against Australia on Sunday, saying every player showed character to come out with flying colours of what has been a tough phase for Indian cricket in the last one-and-a-half-years.

"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.
