Effusive in his praise for national cricket coach Ravi Shastri, former India captain Sunil Gavaskar on Saturday called him an "incredible" mentor with an "unbelievable" ability to motivate youngsters even in their lowest phases. Gavaskar`s view was seconded by the national team`s bowling coach Bharath Arun. "Just 10-15 minutes with Ravi Shastri after a practice session. You know Ravi has got the ability to give so much confidence to youngsters, it`s unbelievable," Gavaskar said during a webinar to mark the book launch of `1971: The Beginning of India`s Cricketing Greatness` published by Harper Collins.

"If he (Shastri) believes in their ability and talent, there is no better man than Ravi Shastri to give encouragement to that youngster. He will scold you, tell you off but at the same time, he will tell you what you can do to get better, he will actually demonstrate to you," said Gavaskar. The batting icon was also all praise for Arun, who has groomed a world-class crop of fast bowlers playing in the same era, a rarity in Indian cricket. "Then you have Bharat, when you talk to some of the seam bowlers who did splendidly during the second half of the Australia tour, they are all full of praise for Bharat as to how he guided them. "That`s what these youngsters need to do. Spend as much time possible with Ravi Shastri and Bharat Arun. There are no better persons than these two when you are having self doubts," Gavaskar said.
