As a player in the Swiss junior leagues for over 20 years, Circhetta often disagreed with the referees, but instead of criticising them, he became a referee himself in 1988. In 2000, he was promoted to referee matches in the Swiss Super League, and five years later he became a FIFA-listed international official.His first UEFA appointment was a third round match between Varteks and Lens in the 2005 UEFA Intertoto Cup."@en .
