Our skipper, who missed the final six matches of last term after picking up a knee injury against Sunderland on 12 April, entered the fray after 61 minutes at Kyle Field, Texas.
Goals from Lautaro Martinez and Giuliano Simeone saw Argentina home. They next play Iceland on Wednesday before kicking-off their World Cup against Algeria on Wednesday week, 17 June.
Elsewhere, Luka Vuskovic was an unused substitute as Croatia beat Slovenia 2-1 in Varazdin. They now travel to the USA and will open their World Cup programme against England in Dallas also on Wednesday week, 17 June.
Meanwhile, all our thoughts are with Christian Eriksen, his family and friends after the playmaker collapsed in Denmark's friendly against Ukraine. The match was abandoned shortly afterwards, but thankfully Christian was able to walk from the field after regaining consciousness.
Speaking this morning, as reported by the BBC, Denmark's national team doctor Morten Boesen gave this update: "I spoke with Christian this morning, and he is doing well. He is with his family and in good spirits. The expectation is that he will be discharged soon and can return home."
