1. Kuldeep Yadav
The glory days of KulCha (Kuldeep and Yuzvendra Chahal) are far behind us. While Chahal is still very much a part of India's ODI and T20I plans, Kuldeep is struggling to find a place in either formats and has even pushed down the pecking order at Kolkata Knight Riders, his IPL team. The 26-year-old chinaman bowler needs some special outings to beat frontrunner Ravindra Jadeja and newbies like Varun Chakravarthy, Ravi Bishnoi, Rahul Chahar etc.
2. Sanju Samson
It was not a long ago that Sanju Samson was touted as the successor of MS Dhoni at least in the white ball formats. But the rise of Rishabh Pant as an all-format wicketkeeper batsman and his own failings have pushed the Kerala man down the ladder. Now, Sanju also has tough competition from Ishan Kishan. His last international outing for India came against Australia away from home in 2020 and it did not end well. He has now been elevated as Rajasthan Royals captain and hopefully a more mature Sanju will push forward his candidature in Sri Lanka.
3. Manish Pandey
After a start-stop career, Manish Pandey seemed to have lost the place in Indian middle-order and Suryakumar Yadav also has been emerged as another option. Similar to Sanju Samson, Manish too played his last international matches on India's tour to Australia and New Zealand in early 2020. He needs some force efforts in Sri Lanka to come forward, especially since his last 50 was in 2017, and hold forth his claim for a berth in the T20 World Cup squad.
4. Prithvi Shaw
Shaw has been on the sidelines since his travails in Australia and New Zealand. Yes, he has showed blistering form in the Vijay Hazare Trophy for Mumbai and looked in decent touch for Delhi Capitals in IPL 2021. It has earned him a ticket to Sri Lanka, and he needs to capitalise fully because Rohit Sharma occupies one part of the opening slot while Shikhar Dhawan is rock solid at the other end. Shaw also has this chasing pack of Devdutt Padikkal and Ruturaj Gaikwad and to break free the 21-year-old Mumbaikar start firing in this series with consistency. It is mandatory for him ahead of the T20 World Cup in October.
