Eddie Jones is being hailed as the saviour of English rugby.
After leading England to a Six Nations Grand Slam earlier this year, Jones completed England's first ever series win in Australia against the Wallabies last night.
The same coach who just eight months ago led Japan to a historic Rugby World Cup victory against South Africa.
But what makes him tick?
Former Australian rugby prop Ben Darwin, who made his debut for the Wallabies in 2001, has shed some light on just how Jones gets the best out of his players.
Darwin, who had 28 caps for the Wallabies, told Tony Veitch on Newstalk ZB that it was Jones' ability to crack the hard shell of players that let him get the most out of his team.
"Eddie understands your deepest fears, about whether your going to be successful or not, and he works on those fears," Darwin said.
"When Eddie walked into the room, there were guys clamouring under tables to avoid Eddie and conversation with him, because he sparked such fear."
Darwin played under Jones for seven years in total and said those seven years were some of the toughest of his life.
"If I was working in any other work place, I would have quit," Darwin said.
"But I wanted to play for Australia, and he knew that, and drives everything out of you."
He also helped coach Japanese side Suntory Sungoliath, where Jones had also done some work, and said he had the ability to come in and transform any team.
"I think the biggest strength Eddie has had, is the immediate impact he can have on a team."
"He's a standard bearer."
Jones has now won eight straight games with England.
