Maradona made the ball an early friend and it was his constant companion in the games of street football that taught him how to compete with older and bigger opponents. Despite this toughening process, however, Maradona's physique, or lack of it, almost cost him his career. The Argentinos Juniors youth coach, Francis Cornejo, had no doubts about his ability - yet could not believe that the little left-footer was old enough to play for his team. His date of birth duly established, Maradona became the star of the 'Cebollitas' helping them go 136 matches unbeaten. The senior squad beckoned, and on 20 October 1976 the 15-year-old debuted for Argentinos Juniors in the first division against Talleres de Córdoba. Another 21 seasons, another bow: the final curtain fell on Diego's career after Boca Juniors' 2-1 defeat of River Plate on 29 October 1997. In the intervening years, Barcelona, Napoli, Seville and Newell's Old Boys had all witnessed the Maradona phenomenon at first hand - a pocket battleship of a player blessed with supreme technique and a magical left foot.
