Eddie Jones has hailed the influence of Dylan Hartley on the rest of the England squad.
England head coach Jones appointed Hartley as captain before the start of the 2016 Six Nations and under the Northampton hooker's guidance the side have gone on to win two Six Nations titles, while also sealing series victories in Australia and Argentina.
Jones, who was appointed in November 2015, believes Hartley's upbringing in New Zealand has aided his ability to lead a side.
"He's a boy from Rotorua," said Jones. "He was up to no good in Rotorua and if you've been to Rotorua there's not much to do there so you've got to find ways to be naughty.
"Then he left and came to England, battled his way at Worcester academy, went through Saints academy - a national team player.
"He knows the value of struggle. He knows the value of how hard he has had to work. Because he leads like that it sets a great example for the rest of the team and now there are at least four or five players that mimic his behaviour."
England play three Test matches against Argentina (11 November), Australia (18 November) and Samoa (25 November) at Twickenham as part of the Old Mutual Wealth series having won 21 of their 22 games under Jones.
And Jones, who was speaking at Soccerex's Global Convention on Tuesday, also gave an insight into how coaching has changed as a result of player behaviour.
He has been coaching for over 20 years including in Japan, Australia and South Africa and explained how he has had to adapt to suit the different needs of the player.
"The players have changed considerably," said Jones. "From 10 years ago, to the players of now, you've got to treat them differently," he said.
"They have got different motivations, different values, and it's neither right nor wrong.
"So, the way you coach them now, you can't just tell them what to do. You've got to guide them to discover what to do. That's the fun part of coaching. If you don't evolve, you don't keep coaching."
