"We've always had a very settled Australian captain with vast experience when you think back to the World Cups - Allan Border's World Cup-winning effort here in India [in 1987], [had] lots of experience," Hayden said at an event in Mumbai. "It was a legacy captaincy, and you could go right down through the ages: Ricky Ponting, [and] Michael Clarke - all World Cup winners, and all [with] vast experience.

"It's got to help, there's no doubt about it. But between the other characters like Steve Smith - you've seen how visible he is when Pat's got the ball in his hand, he's flapping around as he busily does anyway. But he has got a good wingman in Steve Smith as well, again with lots of experience. So, I'm not saying it's a team captaincy, but I think it's a solution that Australia's got covered."

"[Travis] Head and Warner, I think, are your key openers," Hayden said. "[Mitchell] Marsh can do a job. But in all conditions, when you look at the role that Marsh is going to play as an allrounder, I think a specialist opening a World Cup is important.

"But if you're an Australian coach, you'd have no question going, 'We want Marsh to come up and open'. And his role can float in and around the order on any given day if they need to have quick runs inside the powerplay, for example, rather than, well, you talk about Travis; he's still got a strike rate of 96. So it's still an enormous strike rate. But Marsh can be someone that can have an impact at the top if on any given day they need to have a bigger powerplay than any other given opportunity."

"Knowing Australian selectors and the Australian sporting culture, the selectors wouldn't sit around the table and say, 'oh, what does David Warner want in terms of his own playing career?' They would look at it in terms of is he performing and what is our plan as a nation around how it is we project this series, into the next series," Hayden said.

"Because in 2024, India come [to Australia] for the first five Test-match series. So they'll be looking at all those factors, and they'll also be concerned about why it is that they haven't got options aplenty when it comes to replacing David Warner.

"I think back to my time as well, and at that time, there was myself, Greg Blewett, Matthew Elliott there were four or five really great options with strong first-class performances over a long period of time. So we're always having to look at our first-class set-up, and the names that have been always coming around have been [Marcus] Harris, [Matt] Renshaw - these names which are more than capable of producing good Test-match cricket.

"But are they as good as Davey Warner? And the answer is, in their [selectors'] eyes, no. But sooner rather than later, their answer is going to have to be, 'what is our next step?' Now David's saying that's on his terms in Sydney, but I don't think that's necessarily what the Australian selectors will be thinking."

Aaron Finch has retired, and while Cummins might have a few years in him, Nathan Lyon at 35, might not. Usman Khawaja is 36 and Smith and Glenn Maxwell are 34. Mitchell Starc and Josh Hazlewood are 33 and 32, respectively. Thus, the Australian selectors will have a lot to think about soon.

"Australia has always been ruthless, though, around turning over players. In my time, Mark Waugh - who could have played another 50-60 games - gave way to a young Hayden. [That] gave me an opportunity to play 50-odd games ahead of a World Cup, and it paid dividends because I still, a bit like Maxwell was saying, believe that experience does matter in a World Cup.

"When you're under pressure, you've been away from home a long time, you're in the cauldron of Kolkata or over in Chennai where we play India in the first game on the 8th [of October], if you've been there, and done it before, and a lot of these players have played extensive seasons of IPL cricket, [and] have had three or four, five, six, even seven tours of this country. And they've broken the back of India as well in India.

"The last series, I think back in March, was 2-1 [in Australia's favour]. So lots to prove, but also I suppose on the other side of it, youthful talent and also unseen talent can also blast away, and just no one's really seen them, and they take on the world and perform on that stage."
