Biri played as a goalkeeper for a number of clubs, most notably Padova and MTK Budapest FC, also representing Hungary in the 1924 Summer Olympics. He is best known for his coaching career in Portugal which spanned more than three decades.
In 1925, he moved to Italy, representing Padova in the early days of what was to known as Serie A. After two seasons in Italy, he returned to Hungary, passing through several teams, without much success, having short spells in France and Portugal, retiring in 1936, at age 35.
Shortly after, Biri started coaching Porto, winning Campeonato de Porto and coming runner-up in Primeira Liga in his only season there. After a brief spell with Académico Porto, he was then hired by Benfica's President, Augusto da Fonseca Jr. In the eight seasons he spent there, he successfully challenged Sporting dominance, claiming 3 Primeira Liga titles and 3 Taça de Portugal.
He held the record for most games managed and won, for over 75 years, until Jorge Jesus surpassed him in 2014. However, he still has the highest winning percentage of any other coach with at least 100 games and the second longest reign with 8 years, after Cosme Damião.
After Benfica, János managed eleven other teams, retiring as coach in 1966, after more than 30 years in managerial roles.
