Unmukt, the Under-19 World Cup winning captain, attended India Today's Youth Summit to speak on cricket when he is supposed to play a match, which will also feature Sachin Tendulkar, on Saturday.
Unmukt is part of the India 'A' squad which will tour New Zealand soon. The team is currently undergoing a preparatory camp in Bangalore.
"What are you doing here? Why you have come here," is what Kapil asked him when he saw the youngster at the programme.
"If I were his coach or manager, I would not have let him come here even if I was given a million dollars. I would have kicked on his backside for coming here," Kapil said in front of a packed audience mainly comprising youngsters.
When the programme's host jokingly told Unmukt that he was lucky that Kapil was not his coach, the world cup winning captain said actually the youngster was 'unlucky' not to have him as his coach.
"I would have made him work hard for the next three years so that he could live life like a king in the next 20 years."
Both Kapil and Mohammed Azharuddin suggested Unmukt to "stay humble".
"You are outstanding talent, a good player. Stay humble," Azhar said while also urging the youngsters in the audience to "not get into bad habits."
