Born in Treviso, Sartor's Serie A career got off to an inauspicious start, as he scored an own goal past goalkeeper Angelo Peruzzi on his debut (and only game) for Juventus, in a 0–2 defeat at ACF Fiorentina on 6 December 1992.

[2][3] After appearing regularly at Vicenza Calcio, where he played mainly as a central defender, alongside Joachim Björklund, a 2nd place in the league followed in 1997–98 at Inter Milan, with whom he signed a four-year contract,[4] and won the UEFA Cup.

[9][10][11][12] After cancelling his Roma contract in November 2005[13] and six months of inactivity, Sartor moved to Hungary's MFC Sopron, joining Giuseppe Signori and manager Dario Bonetti.

[19] Internationally, Sartor appeared for Italy at the 1996 UEFA European Under-21 Championship, as the nation emerged victorious,[14] also competing the same year at the Atlanta Olympic Games.

[22] An unused member for the under-23s at the 1997 Mediterranean Games, Sartor made his debut for the main squad on 22 April 1998, in a friendly match with Paraguay,[14][23] gaining his second and final cap four years later, against the United States.
