2010 World Cup

Rosetti was preselected as a referee for the 2010 FIFA World Cup. His first match of the tournament was a 1–1 draw between Ghana and Australia. Rosetti sent Australia's Harry Kewell off for handling the ball on the goal line, awarding Ghana a penalty kick. The next game he refereed was the Argentina–Mexico game in the Round of 16, which Argentina won 3–1; the match was surrounded by controversy, however, as Rosetti and his team of officials incorrectly allowed Carlos Tevez's opening goal to stand, even though replays later showed that it should have been ruled out for offside.^[8][9] Rosetti was later left off the list of 19 referees announced by FIFA to take part in the rest of the competition although football's world governing body did not explain why. This decision affected Rosetti greatly and was the major reason behind his immediate retirement following the tournament, although he denied that it was his error that led him to retire.^[10][11]

Later career

Rosetti was hired by the Russian Football Union in 2011 to oversee the domestic referees' department but resigned in 2013 for family reasons.^[12]

In 2018, UEFA announced that Rosetti would become their Chief Refereeing Officer and Chairman of the Referees Committee, succeeding Pierluigi Collina, who became chairman of FIFA's referees committee. Collina assigned Rosetti to be the VAR Refereeing Project Leader at the 2018 FIFA World Cup to help implement the VAR system.^[13][14][15]
