Alexis Sanchez has stated that his Chile side knew that they could score against Mexico, and staying calm was the reason for their comeback after going into the break 1-0 down.
Goals from substitute Esteban Paredes and Arturo Vidal gave Claudio Borghi's men a 2-1 win in their opening 2011 Copa America match, after Nestor Araujo scored for the young Mexicans against the run of play.
