Football is the most popular sport, both in terms of participants and spectators, in the Argentine capital of Buenos Aires.
This has led to the development of several rivalries within the city, contested as "derbys" when the regular league schedule brings these teams together, such as the Superclásico between Boca Juniors and River Plate – deemed one of the "50 sporting things you must do before you die" by The Observer.

Diego Maradona, born in Lanús Partido (county), outside of the city of Buenos Aires but in its metropolitan area, is widely considered 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).
