Sergio Aguero joked that he and Lionel Messi are like "an old married couple" whenever they room together while on international duty with Argentina.
The Manchester City star has been a member of Argentina's senior setup since 2006, having earned 97 total caps while scoring 41 goals.
Aguero is Argentina's third-leading goalscorer, trailing only Gabriel Batistuta and, of course, Messi, who sits atop the country's scoring list with 71 goals.
With Messi having made his Argentina debut in 2005, the Barcelona star and Aguero have become close throughout their careers as they've featured together at three World Cups, four Copas America and during the gold medal-winning run at the 2008 Olympics.
