Silvio Marzolini was an Argentine football player who gained recognition during his tenure on Boca Juniors (1960–72). He is widely regarded as the best Argentine left back of all time, playing that position for the Argentina national football team in the 1962 FIFA World Cup and the 1966 FIFA World Cup, where he was elected as the best left back of that tournament. Marzolini played a total of 28 games for Argentina.

The 1966 FIFA World Cup was the eighth FIFA World Cup, a quadrennial football tournament for men's senior national teams. It was played in England from 11 to 30 July 1966. England defeated West Germany 4–2 in the final to win their first ever World Cup title. The final was level at 2–2 after 90 minutes and went to extra time, when Geoff Hurst scored two goals to complete his hat-trick, the first to be scored in a men's World Cup final. England were the fifth nation to win the event, and the third host nation to win after Uruguay in 1930 and Italy in 1934. Two time reigning champions Brazil failed to get past the group stages as they were defeated by Hungary and Portugal. It was the first time that defending champions were eliminated in the group stages after Italy in 1950. This would not occur again until 36 years later. It was opened by Queen Elizabeth II during the opening ceremony.
