Man City's Sergio Aguero missed his fifth penalty of 2016 but came though Argentina's World Cup qualifying loss to Paraguay unscathed.
City manager Pep Guardiola will be relieved to see that his leading marksman, who has 11 goals in eight matches for the club so far this season, should be fine for the massive month ahead.
But doubts over Aguero's penalty-taking prowess persist after his attempt to equalise from the spot was denied by Paraguay keeper Justo Villar, who was making his first start since this year’s Copa America.
Aguero declared himself fit for the clash in Cordoba, saying he would play for his country "at any cost" after limping out of Saturday's 2-2 draw against Peru with an adductor injury, and was named in Edgardo Bauza's starting XI.
His decision to play was seen as a huge risk, with City facing a tough run of matches which includes a Premier League clash with in-form Everton, two Champions League tussles with Guardiola's old club Barcelona and another visit to Old Trafford in the EFL Cup within the next 30 days.
Argentina's embarrassing 1-0 home defeat leaves them fifth in South America's qualifying table and in danger of facing an Intercontinental play-off to reach Russia 2018.
In other games, Brazil comfortably beat Venezuela thanks to goals from City's Gabriel Jesus and Chelsea star Willian.
