Jeremy Guscott has predicted an "entertaining" ride for England over the coming years following an impressive start to life under Eddie Jones.
The Red Rose followed up their Grand Slam success with a series whitewash of Australia, making their poor showing at last year's Rugby World Cup on home soil a distant memory.
England beat their own record for points scored in a game against Australia twice during the series, which ended with a 44-40 win in Sydney on Saturday, with Jones taking the national side from eighth in the world up to second.
Guscott is now expecting great things in the build-up to the next World Cup in Japan after a historic year to date under the new head coach.
"England's whitewash of Australia is a massive result," he told BBC Sport. "Northern Hemisphere teams normally struggle to win one Test away from home, let alone two or three, so it is a huge achievement. Each team wants to create its own history by winning Grand Slams, World Cups and the like, and this team has done that.
"The series win ranks very highly in English rugby's achievements, although I wouldn't go comparing it to reaching a World Cup final, let along winning one. England have traditionally been poor on their summer tours because they come at the end of exhausting seasons, but the enthusiasm and energy coach Eddie Jones has injected into the squad led to this superb 3-0 result.
"His encyclopaedic knowledge of modern rugby has enabled him to get the best out of this England team. He's pushed them psychologically and physically, asking good questions of them about what they want to achieve, and explaining clearly how they have to go about achieving it. I love his comments to players, the media and the public and I think we're in for an entertaining time in the run-up to the 2019 World Cup."
England are still yet to lose a match since Jones replaced Stuart Lancaster as boss in November 2015.
