England midfield backs George Ford and Owen Farrell can develop into "legends of the game", says the national team's skills coach Glen Ella.The pair start Saturday's second Test in Melbourne with England seeking to clinch a first series in Australia.
"They will both go on Lions tours and win World Cups. That's how confident I am in these guys," Ella told BBC Sport.
"They are great players now - they could be legends of the game in 10 years' time," added the former Wallaby.
After impressing as a replacement in the 39-28 first Test victory in Brisbane, Eddie Jones has restored 23-year-old Ford to number 10 for the second Test, with Farrell - one year his senior - moving to inside centre.
A win against the World Cup finalists at AMMI Park would create history for England and despite winning won four Australia caps between 1982 and 1985, Ella is determined to make that happen.
Speaking to the BBC's rugby correspondent Ian Robertson, he added: "I am Australian, but I'm with England and proud of that.
"I've found it really easy to assimilate with the guys, they have welcomed me.
"We are all here for the same purpose - we want to win and kick the Wallabies up the backside. I'm not here to help Australia, I'm here to make sure we win this series 3-0.
"While we are happy to have won the first Test, we haven't won the series. That's what Eddie and the coaches are driving into the players - we want a clean sweep."
