Ravi Shastri has urged the BCCI to give Umran Malik a central contract with India "straightaway" and says the paceman will be a "handful" in red-ball cricket.
Malik has taken the 2022 Indian Premier League by storm, claiming 21 wickets at an average of 20 for Sunrisers Hyderabad.
The 22-year-old clocked the fastest ball in this year's tournament with a delivery that registered 156.9 kilometres per hour on the speed gun against Delhi Capitals this month.
Malik rattled India captain Rohit Sharma on the helmet and took 3-23 to make another huge statement in Sunrisers' win over Mumbai Indians on Tuesday.
He became the youngest Indian to take 20 wickets in an IPL season with his latest exhibition of explosive pace bowling.
Former India head coach Shastri wants to see the rapid Malik in Rohit's pace attack on the international stage in the near future.
"Central contract straightaway," Shastri said on ESPNcricinfo's T20 Time Out.
"And keep him in the mix, don't let him float around. Keep him in the mix with the main players and then he learns seeing (and) being around with the [Mohammed] Shamis and the [Jasprit] Bumrahs, and see the way they train, see the way they manage their workload.
"Of course, there'll be the team management there, support staff, that'll help him do that, but don't let him stray at the moment. Get him into the mix, and keep him there and groom him."
Shastri says the quick will be even more potent when he learns to bowl with more control.
He said: "He'll get better and better. You see his bowling once he takes a wicket. Look at the lines he starts bowling as opposed to when he has not got a wicket – that's when he is trying everything, his lines are all over the place.
"You don't want him to cut down on pace. The last thing you would tell him looking for control, cut down on pace. What you want him to do is get his lines right: if he can bowl that stump line, attack the stumps on a constant basis, varying his lengths, he will trouble [batters].
"If he gets a wicket and new guy comes in, he can really rattle him because he has got the pace, he can keep the bloke on his toes, but it's that line - if he gets into that channel, without cutting his pace it will make a huge difference."
Shastri says Malik can provide a new dimension to the India Test attack.
"I promise you, this guy is going to be a handful in red-ball cricket. Handful, really. If he is part of an Indian pace battery that has Bumrah, Shami, you add this bloke in, a fourth guy, it's going to be a serious attack," he added.
