KL Rahul is not doing wicket-keeping duties in the IPL due to an injury. If he recovers on time, then he will be the top choice for the selectors.
Rishabh Pant recently returned to competitive cricket and he has performed so far with bat and in wicket-keeping also. He can be named in the squad.
Ishan Kishan has been part of various T20I series recently and has majorly opened for Team India. He can be a good choice as opener and wicket-keeper.
Sanju Samson hasn't latched onto the opportunities he got for Team India but he can read the game well from behind the stumps. He can be a good pick.
Jitesh Sharma has performed well for Team India whenever he got the opportunity with a strike rate of over 150. He can be named in the T20 WC squad.
Dhruv Jurel recently made his debut for Team India in the Test series against England and made a mark with his bat and his wicket-keeping abilities.
Wriddhiman Saha is the most experienced wicketkeeper from this lot. He will be the last choice if any of the above isn't available for the selection.
