Eddie Jones' transformative effect on England's fortunes stems from his ability to create a culture of hard work within his squad, according to New Zealand counterpart Steve Hansen.
England's 61-21 Six Nations-clinching victory over Scotland on Saturday saw them tie the All Blacks' record of 18 Test wins on the bounce.
A shot at a second consecutive Grand Slam awaits next weekend against Ireland, who ended the the run of Hansen's side in November.
Having been dumped out of their home World Cup in the pool stage before Jones' arrival, Hansen said England's revival was down to one simple thing.
"Eddie has installed a want and a desire that has not been there," Hansen told the BBC.
"We always thought England had plenty of talent, but did not want to work hard, but they are doing that under Eddie and loving it.
"The harder you work, the more results you get, so it is no surprise they are putting a run together that is pretty impressive.
"Sometimes you get players, we have a lot of them over here, who are very talented, but do not have the work ethic.
"It's not the players' fault, but then someone comes in their lives, a parent, a teacher or in this case Eddie as a coach, who instils a work ethic and creates a vision that excites them and people change their habits.
"It looks like that is what has happened and it is great for rugby."
England's winning streak started in October 2015 under Stuart Lancaster with a 60-3 win over Uruguay that brought the curtain down on their botched World Cup Pool A qualification bid, as Australia and Wales progressed.
