Shreyas has been in good touch with the willow in his recent outings in white-ball cricket. In the two ODIs against the West Indies in the Caribbean, he got the chance to bat at No.5 and played handy knocks of 71 and 69 respectively to play a crucial part in India's victory in the Caribbean Islands.
Even in the just-concluded three-match T20I series against Bangladesh which India won 2-1, he played knocks of 22, 24* and 62 respectively and was one of the chief contributors for the hosts with the bat.
"For me personally, they (team management) have given me a heads up that 'You'll be there at No.4'. So just back yourself and believe in yourself'," Iyer, who smashed 62 off 33 balls including five sixes in Nagpur on Sunday, said at the post-match presser.
Since last two years, the Men in Blue have tried many players at the number four spot in the lead up to the 50-over World Cup. However, none of them could cement their place in the team.
Iyer believes he can be one of the finishers whenever Virat Kohli and Rohit Sharma fail to perform at the top of the order.
"Even if Kohli and Rohit get out, we need someone to finish the game and bat till the end. That is a No. 4's role. That's what I was trying to replicate today and it worked out really well for me," said the 24-year-old.
Iyer, while admitting there's a stiff competition in the team, said he always tries to compete with himself and looks on improving his game. "Yes, obviously there is lot of competition going in the team. I personally feel that I compete with myself. I don't want myself to be judged with anyone or when you say that this position is empty in the team."
Iyer, who has played nine ODIs and 11 T20Is till now, is however, flexible and ready to bat at any position the team wants him to bat.
"I am really open-minded and can bat at any number. So I just like to back myself in tough situations and today's innings showed that I can bat under pressure as well," he said.
"The support staff have given me the freedom, not just me but all the batsmen, that you need to have that intent when you go in there. And you should feel very positive when you're batting. If the ball pitches in my area, I am not going to control myself. I'll bat according to my instincts," he added.
