Orsi became assistant coach of
Roberto Mancini at
Lazio in 2002. He followed Mancini at
Inter Milan two years later. He left Inter in 2006 in order to pursue a career as head coach. Initially rumoured as possible
Arezzo coach in 2006–07, he was surprisingly appointed to a
Serie A job on 21 March 2007 by
Livorno chairman
Aldo Spinelli in order to replace
Daniele Arrigoni. He made his debut with a 4–1 home win to
Catania on 1 April, leading his side to a mid-table finish in the
2006–07 Serie A season. However, a disappointing start to the
2007–08 league campaign resulted in only two points after the first seven matchdays, convincing Spinelli to sack Orsi on 9 October, making him the first coach to be fired in the season. He was called back at the helm of the
amaranto on 28 April 2008, after Spinelli decided to dismiss
Giancarlo Camolese from the team's head coaching post, but did not manage to save his club from relegation to
Serie B. He then served as head coach of
Lega Pro Prima Divisione club
Ternana from October 2010 to February 2011. ==References==
