Big picture
This is arguably the biggest rivalry in the history of the tournament. Fans have dubbed it the IPL's El Clasico. Mumbai Indians ended Chennai Super Kings' three-match winning streak earlier this month. And while Super Kings are yet to lose a home game this season, the last team to beat them at Chepauk were Mumbai, in IPL 2015, breaking a two-year streak. Super Kings have a 44% win record against Mumbai, while it's 60% or above against every other team. Since 2015, Mumbai have won five of the seven meetings between the two teams.
All this sets up a perfect contest, as Mumbai face table-toppers Super Kings at a crucial stage in the tournament.
While Super Kings have all but sealed their spot in the playoffs, Mumbai are looking to solidify their position, with the race firing up. They're coming into the game following a five-day break after their loss to Rajasthan Royals. A win here would lift them to second, while a loss could land them in trouble, leaving their playoff hopes dependent on other closely-competing teams' results.
Super Kings went into their last game, against Sunrisers Hyderabad, facing questions over whether their batting was too dependent on MS Dhoni. They answered some of them, with Shane Watson and Suresh Raina stepping up to lead the chase of 175, and Dhoni didn't even come out to bat. There are, however, concerns surrounding Ambati Rayudu and Kedar Jadhav, who have been in middling form this season.
Rohit Sharma, meanwhile, has struggled to convert starts, but his form does not seem to be that big a concern yet for Mumbai, who have an enviable degree of batting depth. After producing slow turners in the first half of the tournament, a batting-friendly track was laid out at the MA Chidambaram Stadium on Tuesday, which is good news for the visiting team. Hardik Pandya's late assault ended Super Kings' last major unbeaten home streak in 2015. Can Mumbai take down fortress Chennai yet again?

Strategy punt
Quinton de Kock has been a force for Mumbai at the top of the order, having made 378 runs in 10 games. He's coming into this match with four consecutive 30-plus scores, including two fifties. But this year, he has managed only 114 off 99 balls against spin while being dismissed four times in eight innings. In the IPL since 2015, de Kock has lost his wicket 13 times in 25 innings to spinners. Super Kings could introduce spin early to counter the de Kock threat. Harbhajan Singh, who has had plenty of Powerplay success against left-handers, would be the obvious choice for this match-up.
Suryakumar Yadav might be one of Mumbai's biggest assets, but this season he hasn't really taken off, particularly struggling in the middle overs against spin. In nine innings, he's lost his wicket three times to spinners and has scored just 107 off the 91 balls he's faced from them. A possible fix for this could be Mumbai sending in Ishan Kishan or Kieron Pollard earlier. Kishan has been aggressive against spinners, striking at 163.1 since 2018 in the IPL, while Pollard's best scores (83 v Kings XI and 46 not out v Sunrisers) this season have come when he's entered within the first 12 overs of the innings.
Stats that matter
Hardik Pandya has an average of 42 in the death overs and has been striking at 207.9 in this phase in nine innings.
Raina needs one more fifty to bring up 50 fifties in T20s and one more catch to get to 100 catches in the IPL
Dhoni is one big hit away from 200 sixes for Chennai Super Kings
