Calcutta: Team India bowling coach Bharat Arun is happy with the variety of talented bowlers at his disposal that makes the attack a potentially lethal one.

“We are blessed to have a bowling attack that’s so versatile and each bowler’s needs are different from the other. I feel that my job is to give them the right feedback that helps them evolve as a bowler,” Arun told reporters at the Pallekele International Cricket Stadium in Kandy, on Tuesday.

To add to the already available variety, Arun is looking for a left-arm pacer.

Since Zaheer Khan’s departure, India have not found another capable left-arm fast bowler. Ashish Nehra, despite his injuries, have done well in the shortest format for some time, but Jaydev Unadkat had lacked pace.

Barinder Sran had faded away rather quickly and Aniket Chaudhary was still developing.

In his second stint, Arun expects to interact more with India A team chief coach Rahul Dravid and bowling coach Paras Mhambrey.

“I have just come into this role, so definitely we will be speaking to the coaches of the A team and I guess there needs to be information that needs to be shared for us to make best use of bowlers coming in.

“We have wrist spinners like Kuldeep Yadav and Yuzvendra Chahal. So, if we can get even one good left-arm fast bowler it will be good for the side. We need one,” Arun said.

He insisted that Ravichandran Ashwin remained a vital part of the squad. Ashwin’s dip in form in ODIs has led many to suggest that it could be an end of the road for the off-spinner, who has played 15 of India's 37 ODIs since the 2015 World Cup.

However, Arun said: “He is an extremely talented bowler, and even if you look at his last ODI, which he played in the West Indies, he got 3 for 28. Ashwin is very, very skillful.”

Asked if he is in scheme of things for the 2019 World Cup, Arun said: “This question should be asked to the selectors. He is very skilful. I don’t want to look at what has happened so far, but he is definitely part of the ODI team. We would also like to give a lot of opportunities to other bowlers as well (hence the rotation), then we can have a long-term plan in place and then we will take a call accordingly.”

Arun, who wasn’t not part of the support staff for about a year, said the bowling unit has improved tremendously in the last two years.

“If you look at the bowling unit as a whole, there has been tremendous improvement in the last couple of years. But looking ahead to the 2019 World Cup, we will need to have back-up options for every bowler. There are enough bowlers in our country to provide that bench strength,” he added.

Arun praised Hardik Pandya, who is quickly developing into a reliable pace option for India. “If you look at Hardik, he works up very good speed and bowls 135-plus consistently. He wants to bowl those full 10 overs. And he does understand that to bowl those 10 overs, he needs to work harder. He is not afraid of trying different things. So my job is a lot easier to be working with somebody like Hardik, who wants to upgrade his skill,” the former Tamil Nadu medium pacer said.

Arun added: “It depends on what a bowler is capable of doing... So it is my job to understand that and give them the right feedback.

“Each bowler takes a little time to be able to do that in a match situation.

“You need to put in some hours of practice and you need to perfect that in practice before you are able to put that skill in the match.”

Monitoring the workload of bowlers is also another aspect that bowling coach and the team management has to look into.

“Fast bowling is about 50 per cent fitness and 50 per cent skill. So to remain fit, to bowl fast over a period of time, you have to be extremely fit and that’s one thing that we are emphasizing on,” he said.
