Leonardo Bonucci (Italian pronunciation: [leoˈnardo boˈnuttʃi]; born 1 May 1987) is an Italian footballer who plays as a defender for Serie A club Juventus and the Italian national team.
Bonucci started his career at Viterbese but was loaned to Internazionale in the summer of 2005. He played a number of pre-season friendlies for Inter first team. He then became a member of Inter's Primavera Under-20 Team. Bonucci made his Serie A debut in the last match of 2005–06 season, against Cagliari Calcio.
At the end of the season, Inter bought Bonucci outright. He played his first Coppa Italia match against Messina on 9 November 2006 when he came off the bench for substitute Fabio Grosso in the 86th minute. Bonucci featured in two more Coppa Italia games for Inter that season when he was brought on for the substituted Walter Samuel at half-time during the quarter final second leg match against Empoli and as a starter in the semi final second leg tie against Sampdoria.
In January 2007, 50% of Bonucci's registration rights were sold to Treviso by Inter along with 50% of the registration rights for fellow Primavera Team team-mate Daniel Maa Boumsong. At that time Bonucci was tagged for a peppercorn fee of €500.
Bonucci subsequently remained at Inter until 30 June 2007 while Maa Boumsong returned from Treviso where he spent the first half of the season on loan. During Bonucci's last season with Inter's U-20 Youth Team, he won the Italian "Primavera" U20 Youth League.
At youth level, he played for Under-21 Serie B representative team. He was call-up to the friendly against Renate on 6 November 2007, and against Under-20 Serie C representative team on 4 December 2007. He also capped for the team in an internal friendly, which split the Under-21 Serie B team into two on 9 October 2007, on 21 October 2008, on 25 November, and on 24 March 2009 as blue team captain.
He also received a call–up from Italy U20 team on 31 May 2007. He was an unused bench in the match that 0–1 lost to Serie D Best XI. Bonucci made his debut with Italy senior team on 3 March 2010, in a friendly match against Cameroon which took place in Monaco.
He was included by Marcello Lippi in the starting line-up along with national team regulars Fabio Cannavaro and Giorgio Chiellini to form the defense line in a 3–4–3 formation. Then he was included in the squad for the 2010 FIFA World Cup. He scored his first goal on 3 June 2010, in a 1–2 friendly loss against Mexico. In the World Cup, he appeared as unused substitutes for all three matches played by Italy.
