With 18 points from 13 games, a win will give them 20 points, which is unlikely to be achieved by any other team.
In their previous match against Delhi Capitals, skipper Dhoni and Suresh Raina guided the team to a challenging 179/4 and then restricted the opponent to just 99. Imran Tahir and Ravindra Jadeja shared seven scalps between them as they wrecked havoc.
In contrast, Kings XI Punjab, who are already out of the play-offs race, would be playing only for pride. With 10 points from 13 games, they are at seventh spot, a rung above bottom-placed Royal Challengers Bangalore.
Not being in the reckoning for playoffs will be a disappointment for the home crowd in Sunday's match but they will hope that KXIP finish on a high.
In the previous game against KKR, despite posting a challenging 183/6, visitors' openers Shubman Gill (65 not out) and Chris Lynn (46) took the match away from the KXIP.
Their in-form openers Chris Gayle and K L Rahul, who have been among runs, would be keen to come good against CSK. The likes of Sam Curran, Mayank Agarwal and Nicholas Pooran will have to shoulder more responsibility in the middle-order.
