Brazil, Spain, Britain and Mexico have been chosen as seeded teams for the men's Olympic soccer tournament and will be kept apart at Tuesday's group-stage draw. The draw will separate European and Latin American teams.
In the 12-team women's draw, Olympic champion United States, world champion Japan and Britain are the seeded and will be kept apart in the four groups.
Britain, with a men's team at the Olympics for the first time since 1960, will lead Group A. World champion Spain will headline Group D. Brazil, the best men's soccer team in Olympic history, is the seeded team in Group C.
Senegal became the last of the 16 teams to qualify. They beat Oman 2-0 on Monday in the final qualifier at Coventry's Ricoh Arena, one of the six host venues for the games.
