Born in Novara, Ettore Reynaudi played for his hometown team at the beginning of the career and then played for Juventus FC before and after World War I until 1919, before returning to Novara Calcio until 1927. The first match for this midfielder with the Italian national team was a friendly with the Netherlands in Genova in May 1920, just three months before the Antwerpen Olympic Games where he played two matches against Egypt and Norway. By coincidence, his last match in the Azzurra jersey was against the Netherlands in Amsterdam.
