Vikram Rathour has cautioned Rishabh Pant and other youngsters in the Indian team to avoid playing reckless strokes while embracing a fearless approach.
The 21-year-old Pant has emerged as MS Dhoni's natural successor as the first-choice wicketkeeper of the side but his explosive style of batting has been viewed with skepticism by pundits.
Pant made his Test debut last year in England, where he also registered his maiden century but his manner of dismissals is often met with criticism.
"Of course we want him to play all his shots," India's new batting coach Rathour told reporters ahead of the second T20 against South Africa.
"He needs to be fearless because that is what makes him special. He is an impact player but at the same time he cannot afford to be careless.
"He is a phenomenal player. (But) he needs to bring a little discipline into his cricket.
"All the young players should understand that there is a fine line between fearless and careless cricket."
The first game of the three-match series between India and South Africa was abandoned without a ball delivered owing to relentless rain.
Rathour emphasized the Virat Kohli-led Indian team was keen on elevating their performances in T20 cricket as part of their plans of preparing for the T20 World Cup next year in Australia.
"In the past T20 was not taken seriously. Now since you are preparing for the World Cup all these games are going to be extremely important," he said.
"And I think the next 20-21 games we will be playing will be our preparation for the World Cup."
