Kartik, during a virtual interaction with the media, said the series is crucial for India's spin attack as Ravindra Jadeja approaches the twilight of his career. So, from that point of view, from a red-ball point of view, Manav Suthar was very important," Kartik said. Kartik said Kuldeep Yadav has been a match-winner for India but has not received a consistent run in Test cricket. With Ravindra Jadeja nearing the "twilight" of his career, he believes it remains to be seen whether Kuldeep can emerge as India's next spin leader. He also stressed the challenge of replacing the contributions of veteran spinners and said the Sri Lanka series could determine whether Kuldeep Yadav can emerge as India's spin leader.
