London - Wallaby great Michael Lynagh has said an England 3-0 series win when they tour Australia in June is a "realistic" ambition for Eddie Jones's side.
Australian coach Jones, the first foreigner to take charge of England, was brought on board after last year's World Cup.
That event saw England become the first World Cup hosts to be knocked out in the first round, with a 33-13 defeat by Australia at Twickenham in October sealing their fate.
But under Jones, England have undergone a revival and this season saw them win the Six Nations with a Grand Slam.
It was their first clean sweep of their European rivals since 2003, when just months later England beat an Australia side coached by Jones in the World Cup final.
"Eddie's going down there to win the series 3-0 and why not? It's realistic. It's a good squad," former Australia flyhalf Lynagh told the BBC.
"The only thing is, it's the end of the season and a lot of the England players will be involved in Premiership and European finals.
"It's going to be a fascinating series," added Lynagh, who scored an Australian record 911 points in 72 Tests from 1984-1995.
England are unbeaten since Jones, who guided Japan to a stunning win over rugby union superpower South Africa at the World Cup, took charge.
Lynagh, who finished his rugby career with London club Saracens, believes Jones has restored a bullish belief to England's play that was missing under former coach Stuart Lancaster.
"He's come in and said 'we are going to be arrogant, we have to be like that to win'," said the 52-year-old.
"I think Eddie looks at the culture of English rugby and there is a perception that arrogance is part of it -- so he's said we'll go and do that," added Lynagh, three years into his recovery from a stroke.
"He's not trying to 'Australianise' England. It would be wrong to do that, you have to come in and work on what culturally works within the country."
