Paul Farbrace, England's assistant coach, believes Ben Duckett could slot into the middle order for the Test matches against Bangladesh following his impressive first worldwide series.
"The way he has batted out here, he has looked like he's been batting on different pitches", said Farbrace.
Farbrace said: "One hundred per cent, he will definitely be captain in India".
The abiding sense that each tourist took plenty from it - be that the long hours bonding over matches of Federation Internationale de Football Association on a games console, to the experience on unfamiliar tracks in hostile (in every sense) climes, to the accelerated development of being thrust into a leadership role - was backed up by Farbrace, who said: "For a lot of young blokes it's been a good learning experience".
"He's on this trip as the second 'keeper to start with, but if he gets an opportunity and plays that way again, there is no reason he can't get back into the side. He's showed real maturity with the bat and looked high quality". There can't be any way around it.
Change will not come now but the message from Farbrace was that no one is untouchable and this series reinforced the depth at England's disposal, especially among batters, but Jake Ball's rise was encouraging, too.
With skipper Eoin Morgan sitting out the Bangladesh series over security concerns, wicketkeeper-batsman Jos Buttler was tasked with leading a young and inexperienced squad against a side that had won their six previous home ODI series. Followed by their two-match series against Bangladesh, they will head to India to lock horns with the number one team in the ICC Rankings in a five-match series.

In 2008, the singer-songwriter won the Pulitzer Prize for his contributions to music and American culture. He continued: "If you're a "music" fan, look it up in the dictionary".
Farbrace said: "On and off the field, we have seen he has more to him than others thought". The cricket challenge is only one side.
Bangladesh remain unchanged while England have made two changes, Sam Billings and Liam Plunkett coming in for injured Jason Roy and David Willey.
Cook is now at home for the birth of his second child, meaning he misses the four days of warm-ups which begin in Chittagong on Friday ahead of two Test matches. He is expected to be back in time for the first Test.
But coach Paul Farbrace says they could both still make the line-up, with Duckett also a candidate to replace Gary Ballance at No4.
There was further controversy at the end of the match when the players were shaking hands as Stokes seemed to confront Tamim Iqbal, with England coach Trevor Bayliss stating the Durham all-rounder was trying to stand up for his team-mates.
Billings, playing his first ODI in more than a year and first at the top of the order after replacing the injured Jason Roy, contributed a fine 62 while Duckett registered his second fifty in only his third global match.
