As a teenager, he was sent to London to study in one of the most important centers of the time, and during his years in the British capital, he developed a deep interest in football, becoming a member of Arsenal F.C.

[4] He experienced promotion to the First Division as a member and later, now more closely linked to the board, witnessed the 1934 Spanish cup final, in which Valencia lost 1–2 to Real Madrid.

[3][4][8] In those difficult moments, his work and financial contribution were essential; in fact, he delayed his wedding by investing all his capital in the reconstruction of the Mestalla Stadium, which had been devastated during the war, doing it so alongside Eduardo Cubells, Luis Colina, and the president Alfredo Giménez.

[8][9] On 23 August 1969, the club assembly agreed to name the Mestalla stadium after Luis Casanova, and so it was until the arrival of Francisco Roig to the presidency, who in 1994 returned the popular name to the sports venue.

[3][4][10] The Valencian Casanova family had ties to cinema that dated back to the early 1930s when his brother Manuel founded the Compañía Industrial del Film Español (Cifesa) in 1932, which turned Valencia into the Spanish Hollywood.
