Every team in the competition is set to play tomorrow, with eight matches scheduled.

Among those to feature will be the hosts, who face South Africa at the Estádio Nacional Mané Garrincha in Brasilia. 

Another anticipated clash sees London 2012 champions Mexico take on Germany in Salvador.

The competition has been divided into four groups of four, with the top two in each advancing into the quarter-finals.

Unlike the Women's competition the men's tournament is an under-23 competition, although three overage players are permitted in each squad.

A lot of focus will be on Barcelona forward Neymar, as it was during the 2014 World Cup in Brazil, as he captains a talented home squad aiming to win its first Olympic gold medal.

The Brazilians are favourites to at last win the only footballing title they haven't yet claimed.

For many Brazilians, the men's football tournament will be the most important part of the Games. 

Reigning Olympic champions Mexico should not be discarded, however. 

Although this squad is arguably not as good or experienced as the one at London 2012, there is still plenty of quality.

London 2012 hero Oribe Peralta has been called up as a senior pick once again, while 20-year-old Pachuca winger Hirving Lozano has attracted the attention of a host of European teams.

Germany have re-entered the men's Olympic footballing competition for the first time since 1988, where they won a second bronze medal.

Their group draw appears to be tough though with South Korea also potentially causing them a few issues.

If Germany and Brazil both win their groups and their quarter-finals, they will meet in the last four in Rio, the scene of the Germans' infamous 7-1 crushing of the hosts at the 2014 World Cup. 

The German overage trio includes both Lars and Sven Bender. 

The twins have 26 senior caps between them and, at 27-years old, a wealth of top-level experience with Bayer Leverkusen and Borussia Dortmund respectively.

Following Lionel Messi's retirement from international football, Argentina have been forced to look for possible replacements with the Olympics being the perfect opportunity.

Coach Gerardo Martino resigned shortly before the Games after clubs were reluctant to release players, and at one point the idea of not sending a team to Rio was discussed.

Angel Correa of Atletico Madrid is probably the star player of La Albiceleste, who line up against Portugal first, with their over age spaces going to defensive players.

South Korea took bronze at the 2012 games, where they beat Team GB on penalties, and would be delighted with a similar result this time around.

A podium finish means exemption from military duty for the players.

They face minnows Fiji in their opening match and Tottenham's Son Heung-min will most likely lead the line for Shin Tae-yong's side.

Elsewhere in the opening matches, Iraq will face Denmark, Nigeria face Japan, Sweden take on Colombia and Honduras face Algeria.

The final is to be played on August 20 at the Maracanã Stadium.
