Manchester City striker Sergio Aguero scored twice as Argentina secured a 2-0 victory over Bosnia and Herzegovina in football friendly here Monday.
Playing without superstar striker Lionel Messi, Argentina dominated the tempo most of the match against the Bosnians, who like the Albiceleste, have already booked their place at next year's World Cup in Brazil.
In-form Aguero opened the scoring on 40 minutes after Stoke City goalkeeper Asmir Begovic was unable to snuff out the danger which ensued after a cross from Napoli's Federico Fernandez.
Aguero doubled his tally on 66 minutes, rifling a left-footed shot past Begovic following a swift break in the area.
It was another lethal exhibition of goalscoring from Aguero, who has scored 13 times in all competitions for Premier League side City this season.
Argentina, with only one loss in 12 matches, were coming off a goal-less draw with Ecuador three nights earlier.
That lone defeat came at the hands of Uruguay in a qualifier after a 2014 World Cup berth had already been secured.
In Sydney, Tim Cahill equalled Australia's national goalscoring record to give new coach Ange Postecoglou a winning start in a 1-0 win over Costa Rica yesterday.
The New York Red Bulls forward scored with a header in the 69th minute to give a young experimental Socceroos team a deserved win over the 31st-ranked central Americans.
With his goal Cahill equalled Damian Mori's all-time Socceroos goalscoring record of 29 goals.
It was Postecoglou's first game in charge as national coach since German Holger Osieck was dumped following back-to-back 6-0 defeats to Brazil and France in September and October.
Lucas Neill became Australia's longest-serving captain with his 61st cap, while Cahill played his 65th international for the Socceroos, who are preparing for next year's World Cup finals in Brazil.
