Eddie Jones believes England's lack of success since claiming the 2003 World Cup is a result of successive regimes allowing the team to develop a soft underbelly.
Until Jones masterminded a first grand slam in 13 years, the Red Rose had managed to win just a solitary Six Nations title since Martin Johnson raised the Webb Ellis Cup in Sydney.
The Australian's priority after succeeding Stuart Lancaster in December has been to restore the snarl to the team which he reckons was lost amid players' pursuit of commercial interests.
When asked if the team had become soft since 2003, Jones said: "Without a doubt. I came up against them as Wallabies coach in 2004 and they came out for a holiday. We put 50 points on them in Brisbane.
"You cannot accept that - as soon as it was accepted, it was the end of that team and era. In reality, England rugby has never recovered since.
