Born in Treviso, Buso initially began his career playing as a striker or as a centre-forward with Juventus in Serie A in 1985, at the age of 16, immediately winning the 1985–86 Serie A title and the 1985 Intercontinental Cup, although he was mainly a reserve player at the club, behind forwards Aldo Serena, Ian Rush, and Alessandro Altobelli. He later moved to Fiorentina in 1989, where he was deployed alongside Roberto Baggio and Oscar Dertycia as a winger, or as a supporting striker. During his time at the club, he played and scored in the 1990 UEFA Cup Final against his former team, although Fiorentina would lose the tournament. He subsequently moved to Sampdoria in 1991, where he won the 1991 Supercoppa Italiana. He began to be deployed as a midfielder as his career progressed, and he later also played for Napoli (1993–1996), Lazio (1996–97), Piacenza (1997–2000), Cagliari (2000–01), ending his career with La Spezia in Serie C1 (2001–04).
Buso has also represented Italy at youth level at the 1992 Summer Olympics, and at the 1992 UEFA European Under-21 Championship under Cesare Maldini, where he helped Italy to win the tournament, finishing as the top goalscorer, with 3 goals over the semi-final against Denmark, and the final against Sweden. In total, he made 5 appearances for Italy's Olympic Squad, and 25 appearances for the Under-21 side, scoring 9 goals.
On 17 November 2011 he becomes the new coach of Gavorrano in place of the sacked Guido Pagliuca. He was dismissed in April 2013, with Gavorrano in deep relegation zone under risk of leaving professional football, and replaced by Corrado Orrico.
