Argentina, Brazil rivalry to the fore

Fans from both nations, always willing to taunt each other, have put on a show in the Olympic stands in the first days of competition in Rio. 

When Argentina faced Nigeria in the basketball tournament, fans from both countries ignored the game to taunt each other. 

Local fans openly rooted for Novak Djokovic of Serbia in his match against Juan Martin del Potro of Argentina. 

A couple of days earlier, the Brazilians also cheered for every opponent from eventual judo gold medal winner Paula Pareto, as well as every Portugal goal in its 2-1 win over Argentina in men’s soccer. 

The Argentines chanted a popular song making fun of Brazil’s 7-1 loss to Germany in the 2014 World Cup.
