England coach Eddie Jones insists his team will be prepared for all eventualities as they seek to wrap up a 2-0 series victory over Argentina.
Jones is expecting a backlash from the Pumas in the second Test in Sante Fe following their last-minute 38-34 defeat in San Juan, warning England's opponents may go back into their shells after their expansive approach proved so costly in the end.
"I think it might be a bit of a slug-athon," Jones told a press conference. "It is very rarely that you get two games the same.
"It is like drinking a beer, the first beer never tastes the same as the second beer and the third beer never tastes the same as the second one. Rugby is the same.
"If the first game has been open, the second game has been tighter so we are prepared for both.
"We have made a few changes to have a slightly stronger team and we feel well equipped to handle the occasion."
Meanwhile, the French rugby federation has been reprimanded for failing to follow head injury assessment (HIA) protocols during the conclusion to March's RBS 6 Nations win over Wales in Paris.
Wales' interim head coach Rob Howley said the "integrity of the game had been brought into disrepute" after France replacement prop Uini Atonio went off for a head injury assessment, with starting tighthead Rabah Slimani then returning.
But an untoward incident review group (UIRG) appointed to investigate the incident concluded "there was no clear evidence that there was any intent to obtain a competitive advantage".
Slimani had earlier been replaced, but the France team doctor insisted Atonio needed an HIA, allowing Slimani to go back on as Les Bleus laid siege to Wales' line through a series of scrums.
Wales' view was the HIA process had been used as a method of getting superior scrummager Slimani back on as France looked to exert set-piece dominance in pursuit of a winning try, which duly happened in the 20th minute of stoppage time.
