"I have no intention to walk away from cricket. Chris Rogers waited until 35 years of age to play his second Test. I'm 34 not 37 and I want to keep playing for Australia beyond this series, however I will be judged on performance like everyone else."
Should Clarke carry on playing and continue to struggle for runs, there is a real possibility that he will be dropped from the side, the first Australian captain to experience such an indignity in Test matches since Bill Lawry in 1971.
"I'm enjoying playing now but in time I won't be the guy playing at 38, 39, 40," Clarke said. "I hope I can have my impact in a short space of time and then be finished. I have so many goals I want to see this team achieve and when my time is up, it is up.
"I would love to see the team have success, achieve what it can achieve. And then I think that is time for me to give the reins to somebody else and go and start the other side of life I guess ... get involved in some sort of business and have a family, and do all the things that are special to me and I still want to do when my cricket career is over."
