Chahal has got Maxwell out on all three days with Maxwell being stumped in back-to-back games.
"My plan to Maxwell is not to bowl at the stumps. That's a wrong area. I tend to bowl outside the off-stump and I vary my pace. I know that if I can bowl 2-3 dot balls, he will step out and try to play an aggressive shot. However, in order to beat the batsman, the line and length has to be perfect," Chahal said at pre-match press conference.
"Warner is Australia's key player. When he settles in, he can play the big knock. Although Aaron Finch scored a century in Indore, Warner is the most dangerous player," Warner said.
"He has the experience of playing in the IPL and his mindset is to attack. If he plays 40-50 balls, he can score 70-80 runs. Our main aim is to get Warner out quickly so that in the middle overs, we can maintain the pressure," he added.

Talking about the edge over Australia, Chahal said Indian spinners made the difference, for they bagged 13 wickets compared to Australian spinners.
Chahal feels that when batsmen put up a good score, it gives the bowlers more confidence.
"If batsmen put up a good total on the board, then it gives the bowlers more confidence to bowl well. In the middle overs, we have bowled pretty well, be it the Sri Lanka series or in this series," he said.
"In the last game, they were 234 for 2 after 38 overs. From that position, they were restricted to 293. It was a great exhibition by medium pacers at the death. Whatever spell the spinners are getting towards the end overs, we are getting wickets," he said.
On bowling in tandem with Kuldeep Yadav and Bengaluru wicket, Chahal said he knows the UP chinaman for a very long time and both plan things in a better way by deliberating on bowling strategies before the matches.
The newest spin twins are enjoying each other's success.
"The combination is good. Before the match, we discuss what the wicket will be like. We also discuss what ball to bowl to which batsmen. We always have plans," he added.
Chahal said that the nature of Chinnaswamy track has changed in the last couple of years and has something for spinners.
On ICC rules for size of the bat, Chahal said, "I am not aware of any player in the Indian team changing the size of the bat.
