England coach Eddie Jones has the experience to reinvent himself and turn the nation's fortunes around before next year's Rugby World Cup in Japan, Australian great John Eales says.
England have lost six out of nine games this year, including a 2-1 series defeat to South Africa in June.
They also finished fifth in the Six Nations, which they entered as champions.
"I would never underestimate his ability to turn things around, very, very quickly. He's been around for a long time, and knows how to reinvent himself and tweak things within a team," World Cup winner Eales told BBC Radio.
England's slump has came as a shock after an fine run since Jones' appointment in 2015, which included 18 consecutive test wins and two Six Nations titles.
"He demands high standards, so I can imagine the intensity of that environment will be difficult to maintain over a long, sustainable period of time," Eales added.
"But there is no question England will improve. Anyone who takes England lightly is a fool. They have a lot of talent in the team and a bright guy in charge."
England take on South Africa, New Zealand, Japan and Australia at Twickenham in November.
