Former Austraila captain Phil Kearns thinks Eddie Jones will struggle to maintain success as England head coach due to his coaching style.
Ahead of the three Tests Down Under, pundit Kearns gave an insight into Jones and revealed he could enjoy success before hitting problems.
That is due to his “fanatical work ethic” as Kearns answered the question of whether Jones could well make and then break his playing group.
“I think he will do both,” Kearns told Fox Sports’ The Back Page.
“I think in the short term they will be incredibly successful over the next two to three years – the big question is what happens after that?
“He is a very astute coach but there is a point where the fanatical work ethic goes too far.”
Since taking over as England head coach, Jones has led the team to a Six Nations Grand Slam and is now eyeing the scalp of the Wallabies.
Kearns though believes that his success does eventually come at a cost.
“There’s not a lot of people in the world of Eddie Jones,” Kearns said.
“There’s one bloke – and that’s him.
“That’s his world.
“I actually think he is a good guy.
“But he is massively intense, massively hard working and he ensures his team works hard to the point – I have heard – of overtraining them and really pushing them to the limit.
“I have heard a couple of the guys in the Japan team say they would never play under him again because they could not keep up with the workload it was so intense.”
He added: “It will be interesting to see how over time the Pommies go.”
