The day Reutemann's potential title forced a Superclásico full of stars to be played in the morning

On April 12, 1981, a Superclásico football match between Boca Juniors and River Plate at La Bombonera was rescheduled to the morning to avoid conflicting with a Formula 1 race featuring Argentine driver Carlos Alberto Reutemann. The scheduling adjustment was prompted by the high level of public interest in Reutemann’s potential championship performance, which coincided with the high-profile football match. This event marked the second time within five months that the two sporting spectacles overlapped, necessitating a change in the football match's timing to accommodate the national interest in the racing event.
