Passage: Upon completion of his degree studies at Brera in early 1939, he was drafted by the Italian military for service in World War II. He was deployed to Slovenia, and later to Sicily and Albania, and when his tours of duty were complete, he would participate in art exhibitions. He continued to paint during his service, even when on the front lines, committing to canvas images of "dramatic testimonials" considered prohibited, such as Albanian villages razed by Italian troops. At the end of the war, he also began working on frescoes, glass art, and mosaic art. In 1942, he exhibited works at the Venice Biennale and at the Mostra degli artisti in armi ("Artists in arms") exhibit at the Palazzo delle Esposizioni in Rome, where he presented three watercolours and seven pen drawings, all having a war theme. By this time, he was a sergeant for the Genio Ferrovieri. His first personal exhibition occurred in 1943 and was presented by Raffaello Giolli at the Galleria La Rotonda in Bergamo. He dedicated himself to teaching and the creation of works of sacred art in 1945. He would exhibit at the Venice Biennale again in 1948, 1950, 1956, and 2011, and was invited to exhibit at the Rome Quadriennale in 1952.

Passage: Budai made his debut for Hungary on 2 May 1949 in a 6-1 win against Austria in the Central European Championship. He subsequently played 39 times for Hungary and scored 10 goals. Four of these goals came in a 12-0 win against Albania on 24 September 1950. As one of the legendary Mighty Magyars, he helped Hungary become Olympic Champions in 1952 and Central European Champions in 1953. He also played in the Hungary side that defeated England 6-3 at Wembley Stadium. During the 1954 FIFA World Cup he played in the group stage in the 9-0 win against South Korea and in the semi-final against Uruguay. However, despite an excellent performance in the latter game, he was dropped for the final to make room for Ferenc Puskás. He also played two games at the 1958 World Cup.

Passage: Casillas began his career in Real Madrid's youth system, known as La Fábrica, during the 1990–91 season. On 27 November 1997, at age 16 and still a junior, he was first called up to the senior team squad to face Rosenborg in the UEFA Champions League, although he remained on the bench throughout. After spending a season with the C-team in the fourth tier, during which they won their regional group, he came into contention as the club's first-choice between the posts. In starting the 1999–2000 UEFA Champions League group stage fixture against Olympiakos on 15 September 1999, he became the youngest goalkeeper ever to feature in the competition at the time, aged 18 years and 177 days; a record which was only broken in October 2017 by Mile Svilar. Three days earlier, Casillas had made his La Liga debut in a 2–2 draw against Athletic Bilbao at San Mamés Stadium. In May 2000, he became the youngest ever goalkeeper to play in and win a Champions League final when Real Madrid defeated Valencia 3–0, just four days after his 19th birthday.
