Possible replacements for each position in the Indian ODI squad 

All-rounders

#1 Vijay Shankar

Pace bowling all-rounders are always in demand, this guy has been playing as a back up for Hardik Pandya. He has been shining with the ball and the bat in the A tours and domestic matches. The inconsistency of Hardik might be on the mind of the selectors and also the captain, which means Shankar will be closely followed by the selectors.

He is a very useful batsman and can also give in proper 8-10 overs with his seam bowling combined with his slower balls.

#2 Shivam Dubey

Shivam Dubey was the hottest property in the IPL auction and he has already shown his big hitting capabilities in domestic cricket. If he can show his worth in the IPL, there are high chances he might play for the ODI team, considering the fact he will be closely playing with the captain who wanted him in his IPL side at any cost.

The selectors will also be closely looking at his performances and we never know, he might end up in the ODI team ahead of Vijay Shankar and Hardik Pandya.
