Kohli, who played for India A in the just-concluded second unofficial four-day Test against Australia A, produced knocks of 16 and 45 in the match which the home team won by 10 wickets here today.
India have not played much of Test cricket this year and Kohli's form has been rather indifferent in the ODI arena where he hasn't scored a hundred since February.
"As a batsman I have always been responsible with the way I play my cricket and it comes from wanting to win the game for the team everytime I play. So I don't think I need to change too much in that aspect. I think that is one of the major reasons that the board thought that I could be the man to take up responsibility for the team," Kohli told 'bcci.Tv'.

Talking about the tour of Sri Lanka, which comprises three Tests, Kohli said he is looking forward to leading India for the first time in a full-fledged series.
"It is an exciting challenge to start together as a new unit. It is exciting for me and as a team. Everyone is very very happy and putting in all the effort required to do well in Test cricket. I am certain if we prepare well and have the right kind of vision, we will do really well in Sri Lanka. I am confident about the whole team and also hope that I am able to do the job given by BCCI," he added.
