Natarajan played a vital role in India's victory over Australia in the first T20I.
In his T20I debut against Australia on Friday (December 4) at the Manuka Oval, Natarajan returned with the figures of 3 for 30 in his 4 overs as India defeated the hosts by 13 runs to take a 1-0 lead in the series.
Earlier this week, the left-arm pacer made his ODI debut in the final match of the series at the same venue in which he picked a couple of wickets in the victorious cause.
"What he has done is he has put Mohammad Shami under pressure as a T20I bowler. Now India will be really tempted to have him along with Bumrah as one of his seamers.
"This is a guy who can bowl at the death. If you have Bumrah and Natarajan, it just puts pressure on Shami because Chahar is from a different school of swing," Manjrekar said on Sony Six after India's win in the T20I series opener.
Thanks to his brilliance in the Indian Premier League (IPL) 2020, T Natarajan caught the attention of the selectors and forced his way into the national side.
The 29-year-old plied his trade for Sunrisers Hyderabad (SRH) in the recently held IPL in UAE. He claimed 16 wickets in the cash-rich event at an average of 31.50.
"It’s a great story purely because this is a guy who has come out of nowhere. Today, by playing his first T20I and bowling so well there was a wicket he took off a length ball of Maxwell. He is not a bowler who will get you wickets only with the yorkers when the batsmen are trying to slog you.
"I just find him amazing. A couple of years ago, who would have thought? He would not have imagined himself in his wildest dreams that he would be challenging the big boys for a place in the Indian team," Manjrekar said.
