A metro train metro passes by graffiti, painted in reference to the 2014 World Cup, near Sao Paulo's World Cup stadium, in Sao Paulo, June 4, 2014. Union workers of Sao Paulo's Metro subway system are set to go on strike from midnight. The city's traffic police also plan a strike on Thursday. The wall reads, "In the World Cup. Goal."
