Sándor Kocsis scored 11 goals at the 1954 FIFA World Cup, finishing as the tournament's top scorer and winning the Golden Boot. Only Just Fontaine has scored more goals in a single World Cup tournament. His 2.2 goals-per-game average in the competition is the second highest ever recorded.
Kocsis scored 75 goals in 68 appearances for Hungary, a 1.10 goals-per-game average. His 1.103 goals-per-game average in FIFA Class-A competition across more than 43 caps is the highest ever recorded, ahead of Gerd Müller's 1.097 from 68 goals in 62 games.
Kocsis played for Kőbányai TC, Ferencváros, Budapest Honvéd, Young Fellows Zürich and FC Barcelona. He began with Kőbányai TC as a junior and joined Ferencváros in 1946, later moving to Honvéd through military conscription before emigrating to Spain after the 1956 Hungarian Revolution.
Kocsis left Hungary following the 1956 Hungarian Revolution. Budapest Honvéd were on a European Cup tour when the revolution erupted, and the players chose not to return. After a fundraising tour of Italy, Portugal, Spain and Brazil, Kocsis eventually joined FC Barcelona.
Kocsis died on the 22nd of July 1979, aged 49, after falling from the fourth floor of a hospital in Barcelona. He had been diagnosed with leukemia and stomach cancer. Whether the fall was a suicide or an accident was never conclusively determined.
Kocsis won two La Liga titles with FC Barcelona, in the 1958-59 and 1959-60 seasons, along with two Copa del Generalísimo titles in 1958-59 and 1962-63, and the Inter-Cities Fairs Cup in 1958-60. Barcelona also reached the 1960-61 European Cup final, which they lost 3-2 to S.L. Benfica.
