Coach: Jorge Luis Pinto
How they qualified: Honduras reached the semi-finals of the 2015 CONCACAF Olympic Qualifying Tournament after taking second in Group B to set-up a tense last-four clash against USA. The Stars and Stripes may have been favourites going into the match, but Carlos Tabora’s side stunned the Salt Lake City crowd with Alberth Elis’ brace securing Honduras direct qualification to Rio 2016 at the North Americans’ expense in a 2-0 victory. Honduras fell to Mexico 2-0 in the final, but that result will matter little to Los Catrachos, who are now appearing in their third consecutive Olympic games.

How they qualified: Argentina were the first country to qualify for Rio de Janeiro 2016, courtesy of their South American U-20 Championship triumph in Uruguay in January/February 2015. The Argentinians topped their group in the first round, comfortably beating Ecuador, Bolivia and Peru and losing just the one game, to Paraguay. Maintaining their form in the final phase, they beat the Peruvians once again, drew with Colombia, saw off Brazil and then downed the hosts in front of a 50,000 crowd to secure the title and with it the only direct qualification slot for Rio 2016.

How they qualified: The squad came agonisingly close to adding their names to the prestigious lineage of Portuguese ‘golden generations’ at the 2015 UEFA U-21 European Championship, eventually succumbing to Sweden in the final on a penalty shootout. They reached Rio by impressively topping Group B, beating England before drawing with Italy and Sweden to book their tickets to Rio 2016. In the semi-final, they came up against a much-fancied Germany side, but demolished the Nationalmannschaft 5-0 with a devastating display of midfield dominance. They fell to the Swedes in Prague after a goalless final. William Carvalho cruelly missed the crucial penalty, having enjoyed an otherwise outstanding tournament.

How they qualified: Algeria entered qualification for the CAF U-23 Africa Cup of Nations at the final play-off stage, where they saw off Sierra Leone 2-0 on aggregate, Abdelhakim Amokrane scoring both goals in the ‘home’ leg, despite both matches being played in Bilda due to the Ebola epidemic. That saw the Fennec Foxes into the final tournament, where they finished top of Group B, thanks to a victory against Mali and draws against Egypt and Nigeria. Their 2-0 semi-final win against South Africa confirmed their place in Rio, even though they were edged 2-1 in the final of the tournament by Nigeria.
