Argentina were without Lionel Messi but goals from Angel Di Maria and Lautaro Martinez gave the visitors all three points against Chile in a World Cup qualifier on January 27.
Argentina, who have already qualified for Qatar, opted to rest Messi after his COVID-19 infection but his Paris Saint Germain team mate Di Maria stepped up to give them the lead with a trademark curling shot from outside the box after 10 minutes.
Chile’s English-born striker Ben Brereton equalised just over 10 minutes later when he sent a fine looping header over goalkeeper Emiliano Martinez.
Argentina then took advantage of an injury to Chile goalkeeper Claudio Bravo to seal the win 11 minutes before half time.
Bravo was preparing to be substituted when Rodrigo de Paul fired in a fierce drive from 30 metres, and with the goalkeeper only able to parry the shot Lautaro Martinez followed up to slot home the rebound.
"We knew it was going to be difficult at high altitude and after a long flight," said Di Maria. "The important thing is that we come away with a win.
"Everything is always much easier when Leo is here. The important thing is that we keep working like we’ve been doing and bringing joy to Argentines."
The result, which was also achieved without the presence of talismanic coach Lionel Scaloni, who was isolating at home due to COVID-19, marks Argentina’s 28th game without defeat.
Brereton's goal was the first against Argentina in seven qualifiers.
“Today we were without the best in the world and our coach as well but we got the victory and this is also for them,” said Di Maria.
The result was a huge blow to Chile's hopes of qualifying for Qatar. They are seventh, on 16 points, in the 10-team South American qualifying group with only three matches to play.
The top four qualify automatically and the fifth-placed team goes into a playoff with a side from the Asian confederation.
Leaders Brazil and second-placed Argentina have already qualified and Ecuador, who are third with 24 points, are almost certain to join them.
