Buenos Aires, ARGENTINA: TO GO WITH AFP STORY (FILE) A policeman keeps watch over fans of Argentina’s Boca Juniors 28 June 2001 during the final of the Libertadores Cup against Mexico’s Cruz Azul in Buenos Aires. ‘Barrabravas’ (violent fans) of Boca Juniors teach the ‘ultras’, or hard-core supporters, from Mexico, Colombia, Ecuador and to those of Spain’s Real Madrid, to cheer up their players, but it is unclear if these are merely chanting lessons or a training to beat opponents.
