More than 83,000 fans thronged Buenos Aires El Monumental to watch Messi and co. play for the first time since lifting the countrys third World Cup title last year. After rattling the crossbar with a free-kick, which eventually resulted in Argentinas opener, which was scored by 21-year-old Thiago Almada, Messi curled in a set-piece in the dying embers of the game to hand Argentina a convincing win against the stubborn Central Americans.
