BBC Sport in Rio de Janiero
"The sun is rising on a very big day in Rio de Janeiro - the first match of this tournament at the legendary Maracana stadium. There are plenty of Bosnia-Hercegovina fans here to witness their nation's bow at a World Cup finals, but they are vastly outnumbered because it appears half of Argentina is here to cheer on Lionel Messi & co tonight."
