There are goal scorers, and then there are players, such as Ronaldo and David Villa, who score crucial international goals. Leo Messi? Not so much.
An additional fourth substitute will be allowed in extra-time in matches played at the Rio Olympics and at the Club World Cup later in the year.
Despite success at club level through the last decade, Messi has been criticised for Argentina's 2014 World Cup and 2015 Copa America losses.
"There's always some idiot, to put it mildly. [Messi's] a gentleman. When he scored the goal he raised his hands apologising," River's president said.

Messi returned from a kidney problem to open the scoring in the CWC final versus River Plate, and says the win proves Barca are the world's best team.
