The Arsenal-based forward described his reported confrontation with Chile teammate Marcelo Diaz as "an exchange of opinions".
Alexis Sanchez has played down a bust-up with Marcelo Diaz following Chile's 1-0 friendly win over El Salvador, as Jorge Sampaoli's men aim high for the 2015 Copa America at home.
Sanchez wants Chile to make a statement by winning the continental championship and is convinced his disagreement with Diaz on Friday will not affect the team's preparation.
Diaz was apparently unhappy with Sanchez when he demanded to take a free kick against El Salvador, with the former the designated set-piece taker.
