Speaking on the three youngsters, Steyn said he Vinay was "brilliant" when he spent few years with him at Royal Challengers Bangalore in IPL. For the South African, Ishant is one of his favourites and Umesh is "quick".
"Many years ago when I was with RCB (Royal Challengers Bangalore), Vinay Kumar was brilliant and he has now gone on to represent India. And he is one of the leading wicket takers in this year's IPL, I am still very impressed with him," the 29-year-old Steyn, who is playing for Sunrisers Hyderabad in the ongoing IPL, said.
"Ishant Sharma is one of my favourites. He is tall and runs in and bowls with his height. He has got good speed. Umesh Yadav, I like him. He bowls good spells, he is quick," Steyn added.
Talking about limited overs games, Steyn regarded West Indian Chris Gayle as the most destructive player.
"In shorter format, somebody like Chris Gayle can be very destructive. He can take you to park literally in one over. You might not bowl another over in the game," he said.
The decision of Gary Kirsten to step down as the coach of South Africa after the ICC Champions Trophy next month has not come as a surprise to Steyn.
"I thought it was always coming. Gary is a massive family man, he loves his family. When we were in Australia and we had a 10-day off (break) he jumped on a plane and flew home for three days to be with his family. (His) Stepping down as the T20 coach and allowing Russell Domingo to take over, it was tell tale signs that something was coming.
"I completely understand from where it is coming. I have spent almost 220 days of a year every year for the last five years (playing cricket). That what my life has been. I feel like I want to retire from cricket right now and he has been in this game since God knows. Hopefully he can finish his career with South Africa winning a trophy. That would be fantastic," he said.
Asked about Domingo's coaching skills, he said, "I think he is going to be great. He was in the shadow of Gary. Russell did a lot of work behind the scenes whilst Gary was the head coach. I think it is Russell's turn now to stand up. He is a great coach and he is going to show people what he is capable of."
