Diego Maradona joined Barcelona from which Argentine team?

Diego Armando Maradona (born 30 October 1960) is widely regarded as one of the greatest football players of all time. He was one of the two joint winners of the FIFA Player of the 20th Century award. Maradona's vision, passing, ball control and dribbling skills were combined with his small stature (1.65 m or 5 ft 5 in), which gave him a low center of gravity allowing him to maneuver better than most other football players.

Maradona signed a contract with Boca Juniors on 20 February 1981. He made his debut two days later against Talleres de Córdoba, scoring twice in the club's 4–1 win. On 10 April, Maradona played his first Superclásico against River Plate at La Bombonera stadium. Boca defeated River 3–0 with Maradona scoring a goal after dribbling past Alberto Tarantini and Fillol. Despite the distrustful relationship between Maradona and Boca Juniors manager, Silvio Marzolini, Boca had a successful season, winning the league title after securing a point against Racing Club.

After the 1982 World Cup, in June, Maradona was transferred to Barcelona in Spain for a then world record fee of £5 million ($7.6 million). In 1983, under coach César Luis Menotti, Barcelona and Maradona won the Copa del Rey (Spain's annual national cup competition), beating Real Madrid, and the Spanish Super Cup, beating Athletic Bilbao.
