Chennai Super Kings made good use of the Indian Premier League (IPL) retention policy by holding on to skipper Mahendra Singh Dhoni, all-rounder Ravindra Jadeja and Suresh Raina. The CSK captain Dhoni on Friday said the franchise would be aiming to get Ravichandran Ashwin back in the fold in the upcoming IPL 2018 Players' Auction. The players' auction is scheduled for January 27 and 28 in Bengaluru.
