The second round of the Rio 2016 Olympics men's football round saw Group A giants Brazil succumb to yet another 0-0 draw with Iraq, leaving them with only two points from their first two games. Deemed as one of the favourites for the tournament, the South Americans have to beat Denmark in the next game to have any chance of qualifying.

Neymar and Gabriel Jesus, the stars of the show, failed to put up a good performance in the game and were subjected to loud jeers from fans. Meanwhile, in the other game from the group, Denmark edged South Africa 1-0 to go top of the group and all but confirm a place in the quarters. They will face Brazil next in a do or die game for the South Americans.

In Group C, Fiji continued their torrid run in the competition, being beaten 5-1 by Mexico and were the first team to be eliminated in the competition. The other game saw South Korea hold Germany to a 3-3 draw, with the Germans yet to register a single win in the competition, having drawn their first two games.

The European Champions beat Argentina 2-0 in the opening fixture and are looking good to go all the way in the tournament. In the other Group D game, Argentina beat Algeria 2-1 to make a strong case for qualification into the quarters.

In Group B, Colombia held Japan to a 2-2 draw in an exciting game that saw both teams carve a host of chances. In the other game, Nigeria edged Sweden 1-0 to book their name in the knockouts. The African side had beaten Japan 5-4 in the last game.
