Argentina coach Daniel Hourcade admits his side must improve after a last-gasp defeat to Scotland which has seen them slip out of the top eight in the world rankings.
The Pumas travel to Twickenham next weekend to take on England in the final Test match of a disappointing November tour that has also seen them lose 24-20 to Wales.
Argentina's 19-16 loss to the Scots put them out of the top eight and in danger of not being among the second group of four seeds.
"A very important match is coming up," said Hourcade. "We know who we're facing and I have confidence in these players. We must analyse what the Scotland match showed us and think of England."
In May next year, the world rankings will determine the top eight seeds in the draw for the 2019 World Cup's pool stage.
The November tests were the last opportunity for southern hemisphere countries to earn - or lose - ranking points, and Argentina must now hope that European teams such as Scotland do not fare well in the Six Nations if they are to return to the top eight.
Argentina's November form is in sharp contrast to their showing at last year's World Cup, where they defeated Ireland in spectacular fashion to reach the last four, and veteran centre Juan Martin Hernandez admits the team is still developing.
"There is evidently a lack of experience in knowing how to close down matches," said Hernandez, who laid on Argentina's try at Murrayfield on Saturday for Matias Orlando.
"When you score points you must revalidate them and come out of your half (of the field) to put (opponents) under pressure," he said after Scotland hit back with Sean Maitland's try four minutes later.
Argentina have beaten England once at Twickenham where former captain Agustin Pichot led them to a 25-18 victory in 2006.
England won 31-12 when they last played there in 2013 in Hourcade's first match in charge.
