England will be ready for a tough physical battle with the Argentinian pack, says Wasps forward Nathan Hughes.
Eddie Jones' men were given a difficult time by the Pumas at Twickenham last November before overcoming the early dismissal of Elliot Daly to triumph 27-14.
It was a full-blooded affair with four yellow cards and two reds and Hughes is expecting another potentially feisty clash in the first Test in San Juan on Saturday.
"Before the game in November we expected them to come out firing and with Argentina they have got a good set piece game," said Hughes.
"They like their line-outs and their scrum. In the game, Argentina had 15 v 13 pretty close to half-time and it was scrum after scrum after scrum.
"They didn't want to leave the field without a try. What we expect from Argentina this week is their physicality they will bring in the forwards.
"I think they have moved from top four [in the world rankings] from 2015 to ninth now and they will want to prove a point that they belong up there and not down there."
With 30 players missing through injury, suspension and calls from the British and Irish Lions, Hughes is suddenly thrust into a leadership role as he prepares to win his ninth cap.
"It is more for everybody to take ownership," he added. "It is a young group overall and we have got a few senior boys who will say their bit but Eddie wants everyone to stand up and be a leader.
"We have got Dylan [Hartley] as a captain but he wants everyone to be a leader on the field."
