England lock George Kruis believes his charges need to improve their defence in the second Test against Australia in Melbourne on Saturday.
Kruis, whose side overcame the Wallabies 39-28 last weekend in Brisbane, will be looking to make it 2-0 and secure the series at AAMI Park.
But the Saracens second-row insists the visitors cannot afford to concede as many tries on Saturday if they want to win what's a vital fixture.
"We can improve across the board," Kruis told England Rugby's website.
"We let in four tries at the weekend and if you look at the RBS 6 Nations we didn’t let in many, so defensively we can improve.
"Against a side which has the attacking ability and pace in the backline that Australia do there’s no switching off."
If England win they'll become the first side to win a series in Australia and coach Eddie Jones believes the Wallabies will come back stronger.
Kruis continued: "For us it's a huge Test, they're going to throw everything at us and we want to be a team that is winning home and away.
"Yes we're focused, we want to be a physical and ruthless side so we train like that and we play like that.
"In my eyes they’ve got a very good set-piece and under Michael Cheika they’ve turned that all around.
"I’d love to have a dominance over every lineout that we play because as a pack we strive for consistency across the board.
"This really is the next step for us, it’s the next game and the next thing in front of us. We will put everything into winning this game and we’ll be as desperate as we were last week for this weekend."
