He began on October 28, 2006, officiating the match between Chievo and Livorno. Four years later, he made his European debut for the Europa League qualifier between Ventspils and Suduva on July 15, 2010. In Serie A, Orsato officiated over two hundred and fifty matches. Additionally, Orsato also refereed the Champions League final between Paris Saint-Germain in 2020 and a World Cup semi-final in Qatar in 2022 between Argentina and Croatia. Regarding national competitions, Orsato officiated over twenty matches.
Roma was the team he refereed the most, with 42 matches, followed by Milan (39 times), then Napoli (37), Juventus (36), and Inter (33). Despite his skills and experience, Orsato did not have the opportunity to referee a European Championship final, a coveted milestone for many referees. This has sparked debates among football enthusiasts and the media, considering the talent and professionalism he has demonstrated over the years. His career was also marked by controversial moments, typical in the life of a referee, but his dedication and commitment to football are undeniable. Among the many episodes worth mentioning is a Serie B match between Napoli and Frosinone when, from the stands of San Paolo, some insulting banners towards Franco Carraro, the former federal president, appeared. Orsato decided to stop the game.
Ending his refereeing career without a European Championship final is certainly a curious point in his career, but his contribution to the world of football remains significant and appreciated. The last match Orsato officiated was between England and Switzerland on July 6, valid for the quarter-finals of the European Championship in Germany.
