"He has scored over 1000 runs in the domestic season, looks in really good form with twin hundreds in the Duleep final, so if you are going to give a youngster an opportunity, it's good to pick him if he's in good form and actually playing well. You are picking him, at least initially, as a back-up opener," Dravid told ESPN Cricinfo today.
"In Australia, India will need six batsmen, given the kind of pace attack that Australia has and the wickets they will be up against," he said.
"Pick three quality fast bowlers and a spinner, and hope you put enough runs on the board to give your bowlers enough time to pick 20 wickets."
Dravid wants Karn in the Test squad over Ravindra Jadeja as "wrist spinners have a greater chance to succeed in Australia especially if they bowl slightly quicker in the air and have a good googly."
