Harmanpreet and Sciver-Brunt - fire, ice, and a touch of MI at the World Cup

The difference is stark as you get off the main road and enter the bylane to reach the media gate at the Holkar Stadium in Indore. It's distinctly quiet, free of the honking and the bustle of vehicles. Quite the contrast. Much like Nat Sciver-Brunt and Harmanpreet Kaur at training on Friday, ahead of the crucial game between India and England.

Sciver-Brunt was everywhere. She was partaking in catching and fielding drills one moment. And the next, she was spot-bowling in one of the two training nets. Then she was bowling to Tammy Beaumont and Sophia Dunkley, before batting in the adjacent net against throwdowns and the England bowlers. Not long after, she changed out of her training kit to fulfill broadcast commitments. It was a packed schedule for the England captain on a hot afternoon in Indore.

By the time Harmanpreet and her team strode in, the sun had given way to a dark, cloudy sky. The floodlights came on almost right on cue. There was a drizzle just before India's arrival and so they chose to train in the enclosed Amay Khuraysia practice arena just behind one of the east stands. Harmanpreet was a picture of focus. She batted in pairs with Jemimah Rodrigues and faced a variety of India bowlers. India used two pitches in the facility - a red-soil surface and a black-soil one. She batted on both of them for close to 90 minutes. After that, she bowled to Deepti Sharma for a bit.

Harmanpreet and Sciver-Brunt have had many match-winning partnerships in the WPL for Mumbai Indians (MI), who have won two titles in three seasons. As MI captain and vice-captain, they have plotted the downfall of many of Harmanpreet's India team-mates, including Smriti Mandhana and Jemimah Rodrigues. But come Sunday at the Women's World Cup, the duo will be in opposite camps, plotting to take the other down. England, with seven points, are yet to lose a game in the tournament; India have only four points in four matches after suffering losses in their two previous games.

Harmanpreet will also be up against Charlotte Edwards, who left her job as MI coach after three years to take charge of England. India and England played a bilateral series in July with the MI leadership split across both teams, but this next game is the one that matters most. A full house is expected in Indore.

"In my 15-16 years of coaching, whenever I have had a chance to work as an assistant coach, my best experience was under Anju [Jain] di at Bangladesh. After that, I would definitely take Charlotte's name," MI batting coach Devika Palshikar tells ESPNcricinfo. "She is tactically brilliant. She gave us a free hand, our roles were quite clear. In a short tournament like the WPL, it is important to keep the players in a good space mentally. Charlotte is really good at that."

Edwards seems to have had a similar impact on England's players. Linsey Smith, who has opened the bowling several times in T20Is, was asked to do the role in ODIs for the first time, and she delivered. Emma Lamb had not batted outside the top order in domestic cricket, but she was backed to do a middle-order role, partly because England also need batters who can bowl spin.

"Charlotte doesn't put pressure on the results," Palshikar, who helped bridge the language barrier at MI, said. "It is always about the process. She gives small, specific targets to players. For example at MI, [openers] Hayley [Matthews] and Yastika [Bhatia] have to take care of the powerplay. After that Nat is there, and she and Harman [Harmanpreet] can have a good partnership."

Apart from Edwards and Sciver-Brunt aside, England also have another person from the MI support staff in their camp - Benji Hoppitt, the performance analyst. Palshikar calls him "a mastermind who helps us trick opponents". Edwards and Hoppitt also worked together at Sydney Sixers in the WBBL and Southern Brave in the Hundred.

"Benji has very good insights. He is thorough. He is the best analyst I have worked with so far. We now know why Charlotte and Benji work together everywhere!"

All this is not to say England have the inside track on India. Harmanpreet has been on the international circuit for over 16 years. Perhaps no one moved the needle as much as she did with her 171 not out against Australia in the 2017 World Cup. And even at 36, few can match her for power with the bat.

"Harman is very experienced," Palshikar says. "She's played on Indian soil for close to 20 years. So she knows about the grounds and other things. And she is tactically sound and assured."

Palshikar and Edwards also worked together to help Harmanpreet play attacking cricket from an earlier point in T20 cricket, a move that helped MI lift a second title earlier this year. "Her consistency at the WPL is unmatched," Palshikar says. "The way she plays freely, I actually see a different Harman with us. She has been given a free hand and the confidence reflects.

"Her routines also help her a great deal. She knows how to keep herself mentally and physically fit. She is very professional. She knows to cut off from the outside world, she is thorough in keeping a minimum screen time ahead of games. That is something for youngsters to see and learn."

A sub-plot to this great MI divide is a Royal Challengers Bengaluru (RCB) duel. Luke Williams and Smriti Mandhana, head coach and captain of the title-winning team in WPL 2024, are also in opposite camps. Williams is Edwards' assistant while Mandhana is India's vice-captain.

Palshikar was India's assistant coach when Mandhana played her first T20 World Cup in 2014. The pair also worked together at Ratnagiri Jets in the Women's Maharashtra Premier League (WMPL) earlier this year.

"I was lucky to work with Smriti at WMPL," Palshikar says. "I last worked with her in 2014. The Smriti of 2014 and now the Smriti of 2025 - oh, I was so impressed with her. I have worked with so many players. But [Harmanpreet and Mandhana] are true legends. After Mithali [Raj] and Jhulan [Goswami], India will forever have these two legends."
