(CNN) -- Hosts Argentina needed a stunning late strike from substitute Sergio Aguero to salvage a 1-1 draw against Bolivia in the Copa America opener Friday night.

Argentina could not break down the underdogs in the first half and just two minutes after the break it was Bolivia who took a shock lead as Edivaldo Rojas backheeled a corner past Argentina goalkeeper Sergio Romero.

Marcelo Martins might have put the game out of Argentina's reach as he beat the offside trap but Romero was alert to push the ball away from him before saving a follow-up effort.

A jittery Argentina, with Lionel Messi well below his best, had to wait until 13 minutes from time for the equalizer.

I think that Argentina plays extremely bad because Argentina has the team to score like 5 or 6 goals because they have messi that people said is the best i dont think so but they have higuain that is anexcellent player they also has di maria that is really fast and he plays very good
