I Golden Boy
Nicknamed the Golden Boy of Italian football, Rivera was the product of Alessandria's youth football academy and made his debut in Serie A for Alessandria against Internazionale on June 2, 1959 at the age of only fifteen years. He played 26 matches for his first club, for which he scored 6 goals. A year later, he was bought by AC Milan to replace Juan Schiaffino with a record transfer fee for that time, $200,000. In 1962 he won the first scudetto with AC Milan and on May 13, 1962, aged just eighteen, he played his first match for the Italian national team against West Germany at the World Cup in Chile, a game that finished with a goalless draw.
