Defending champions Mumbai Indians in all likelihood will be retaining skipper Rohit Sharma along with Pandya brothers, Hardik and Krunal, while under- performing Delhi Daredevils may keep Rishabh Pant and Shreyas Iyer in their stable ahead of the IPL auction on January 27. While the last date of submission for the player retention is January 4, the franchises are more or less certain about the kind of players they would like to retain and the ones they would buy back with Right To Match (RTM) cards.
