Football is a passion for Argentines. Buenos Aires has the highest concentration of football teams of any city in the world (featuring no fewer than 24 professional football teams) with many of its teams playing in the major league. The best-known rivalry is the one between River Plate and Boca Juniors watching a match between these two teams was deemed one of the "50 sporting things you must do before you die" by The Observer. Other major clubs include San Lorenzo de Almagro, Asociación Atlética Argentinos Juniors, Club Atlético Huracán, Club Ferro Carril Oeste and Vélez Sársfield.
Diego Armando Maradona, born in Villa Fiorito, a villa miseria in the Lanús Partido (county) south of Buenos Aires, is widely hailed as one of the greatest football players of all time. Maradona started his career with Argentinos Juniors, later playing for Boca Juniors, the Argentina national football team and others (most notably FC Barcelona in Spain and SSC Napoli in Italy).
