Australia coach Michael Cheika said England counterpart Eddie Jones has had an instant impact on the European nation.
Jones replaced Stuart Lancaster following a forgettable Rugby World Cup on home soil last year, and the Australian has already overseen back-to-back Six Nations victories.
Jonathan Joseph scored a second-half hat-trick as England routed Italy 40-9, a week after they edged Scotland 15-9.
"They've been playing much better," Cheika said.
"You look at the way they've been playing and he's given them more belief straight away and that's what I knew he'd do.
"Even in the World Cup it was small margins so I expect them to be at the top of that Six Nations tree and it will be a really good series when they come out here."
Cheika and former Wallabies coach Jones will lock horns in a three-Test series in Australia later this year.
The Wallabies will host England in Brisbane on June 11, followed by fixtures in Melbourne (June 18) and Sydney (June 25).
"He will want to win but his history with Australia is brilliant," Cheika said.
"He took Australia to a World Cup final in his home country and he's influenced a lot of players in the game here so I don't think there's any bitterness.
"He will want to win because he will want to do the best by his team."
