TBH, the CSK batting line-up has been disappointing so far this season. MS has played a couple of important knocks and they have been able to win those important moments in the match. Watson has been very poor so far in the tournament and I think CSK management can give some more chances to Sam Billings. I know Watson has been a proven performer but right now he can't buy a run and is also not bowling and you have to hide him in the field. An exciting player like Sam Billings can be given some more chances considering he can provide that flexibility in the batting order and he is a gun fielder. Other than that, I don't see Dhoni making any other changes even though they are failing consistently in batting.
