Maradona made his professional debut with Argentinos Juniors on 20 October 1976 wearing the number 16 shirt, a week before his 16th birthday. He scored his first goal in November 1976 two weeks after turning 16. In 1981, he transferred to Boca Juniors, and won the league title with them that same year. His performances at the 1982 FIFA World Cup attracted the interest of FC Barcelona, and they signed him shortly after the tournament.
