Lionel Messi and Lautaro Martinez scored twice for Argentina as it concluded its Copa America preparations with a comfortable 4-1 victory over Guatemala. 

Argentina was behind inside four minutes when Lisandro Martinez's own goal handed Guatemala its first goal against La Albiceleste.

However, Messi, who was featuring for the 182nd time for his country, levelled the contest eight minutes later as goalkeeper Nicholas Hagen's poor clearance fell kindly into his path.

Lionel Scaloni's team was awarded a penalty just before half-time as Nicolas Samayoa fouled Valentin Carboni, with Martinez stepping from 12 yards to score.

Messi and Martinez combined for Argentina's third goal, with the latter doubling his tally after he was picked out by his team-mate in the area.

Messi put the result beyond doubt late on, lofting the ball over Hagen after latching on to a fine pass from his former Paris Saint-Germain team-mate, Angel Di Maria.

Argentina kicks off its Group A campaign against Canada on 22 June (AEST) before facing Chile and Peru in its quest to retain its Copa America title.
