SAO PAULO — Argentina will return to Olympic football next year after sealing victory in the South American under-20 qualifying tournament in Uruguay Saturday. The Argentines, winners of the Olympic gold in 2004 and 2008, missed out on London but will be in Rio de Janeiro in 2016 after beating hosts Uruguay 2-1 in Montevideo. The result means that Argentina is under-20 South American champion and grabs the one guaranteed qualification spot for next year's Olympics. Second-placed side Colombia will play off against a team from the Concacaf region for a place in the Games. The Colombians beat Brazil 3-0 Saturday to secure second place in the competition. — Reuters
