Claudio Circhetta

Claudio Circhetta is a Swiss former football referee. 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 NK [Varaždin (1931–2015)|Varteks] and Lens in the 2005 [UEFA Intertoto Cup]. The following year, he took charge of his first UEFA Cup match in the tournament proper, a first round match between Red [Star Belgrade] and Slovan Liberec. His first Champions League group stage appointment was a match between Celtic and Villarreal on 10 December 2008. His most prestigious appointment was as fourth official in the 2009 [UEFA Champions League Final], alongside referee Massimo Busacca. He retired at the end of 2010 to take up the position of Swiss referees chief.
