Early career Vučinić started out at his hometown club
Sutjeska Nikšić before being snapped up by
Lecce in Italy during the summer of 2000 at age 16. The man who initiated the transfer was the club's sporting director at the time,
Pantaleo Corvino, who has since developed a reputation for having a good eye when it comes to football talent coming out of Eastern Europe. In his
fourth season for the club, 21-year-old Vučinić scored 19 goals in 28 Serie A games, including a
hat-trick versus
Lazio on 1 May 2005. Following that successful season, his progress came to a halt with only nine goals recorded in 31 games as his career stalled due to injury.
Roma On 30 August 2006, Vučinić signed a one-year loan contract with
Roma worth €3.25 million, with an option of buying
50% of his registration rights from Lecce at the season's conclusion for an additional €3.75 million. Vučinić signed a 1+4 year contract, which worth €1.07M, €1.6M, €1.8M in the first three seasons in gross annually, Also, the presence of the
European Golden Boot winner
Francesco Totti as the lone forward of Roma's tactical formation under head coach
Luciano Spalletti did not give Vučinić much playing time. Despite this, he succeeded in scoring three goals: his first goal for Roma in the 1–0 victory against
Siena on 28 January 2007, his first goal in the
UEFA Champions League during the
quarter-finals match 2–1 victory against
Manchester United on 4 April 2007. He also scored another Serie A away goal against
Catania in a game that saw Roma beat the
Sicilians 2–0.
2007–08 season At the beginning of the
2007–08 season, Roma paid
Lecce the pre-agreed price of €3.75 million to sign 50 percent of Vučinić's rights. He decided to wear the No. 9 jersey, previously owned by
Vincenzo Montella in the last eight seasons, and also stated that he would like to do the same that Montella did at Roma. As
Francesco Totti was usually deployed as a lone striker, Vučinić began to play as left winger in
Luciano Spalletti's
4-2-3-1. He scored his first goal of the season in the 2–1 victory against
Sporting CP, in the
Champions League group stage, allowing Roma to get the vital goal to earn them three points. In the following game, away to
Milan at the
San Siro, with Francesco Totti injured, Vučinić started as a striker and scored a header, from a cross by his teammate
Cicinho. It was the only goal of the game as Roma picked up a win over their rival. This proved decisive again, as in the game against city rivals
Lazio, Roma won 3–2, with Vučinić leaving his mark with a left-foot equaliser and an assist for
Simone Perrotta's goal. Another decisive goal of Vučinić was a header against
Real Madrid at the
Santiago Bernabéu, securing a 2–1 win for his side as well as qualification to the successive round.
2008–09 season In June 2008, Roma finally bought Vučinić outright by paying Lecce €12 million, meaning Roma had paid €19 million in total to Lecce. On 4 November 2008, he scored two goals in Roma's
UEFA Champions League group stage match against
Chelsea, emerging as 3–1 winners. Roma made it to the
round of 16, where they lost to
Arsenal on penalties, with Vučinić missing the target in the shootout with a weak shot down the middle that was easily saved by goalkeeper
Manuel Almunia.
2009–10 season On 1 June 2009, Roma announced Vučinić had signed a new four-year contract, under which the gross wage of the 2008–09 season would increase to €3.3 million as well as €4 million in 2009–10 season; €4.2 million in the 2010–11 season; €4.5 million in 2011–12 season and €4.7 million in 2012–13 season. The
2009–10 Serie A campaign started off poorly for Roma, forcing head coach
Luciano Spalletti to resign after two opening losses. Arrival of new head coach
Claudio Ranieri initially failed to change matters with the team continuing to slide down the standings. Vučinić was booed by Roma fans in early November 2009 against
Bologna when he finally scored his first goal of the season. After winning that match, however, Roma went on a 24-match unbeaten run in the league, mounting a credible title challenge by the end of the season, in large part thanks to Vučinić's improved form and steady goalscoring efforts that included a hat-trick versus
Udinese and a brace in the win against heated crosstown rivals
Lazio.
2010–11 season The 2010–11 season began well for Vučinić, scoring the injury-time winner against defending league champions
Inter Milan. As the season progressed, however, he experienced a loss of form and his goals output dipped dramatically. Later in the season he was linked with a move to Tottenham. The team was also going through turmoil as it was way off pace for the title after challenging for the
Scudetto the previous few seasons. Head coach Ranieri was sacked and replaced with
Vincenzo Montella. Vučinić's form didn't improve much as his loss of confidence became very evident in April when he missed open net sitters in two consecutive home matches – first in Serie A versus
Palermo with the score tied at 1–1 (Roma eventually lost 3–2), and then three days later in the
Coppa Italia semi-final first leg versus Inter (Roma lost 1–0).
Juventus 2011–12 season On 30 July 2011, it was confirmed that
Juventus had signed Vučinić for €15 million from Roma, with a 4-year deal worth a reported €3.5 million [in net] per year. He scored his first goal for the club on 21 August 2011 in the 2–1 defeat to AC Milan in the annual Trofeo Luigi Berlusconi curtain raiser to the Italian season. Vučinić scored a 32-metre goal in extra time to help Juventus to a 2–2 draw against
Milan on 20 March 2012, helping his side to a 4–3 victory on aggregate and progression to the
2012 Coppa Italia final.
2012–13 season The second season of Vučinić started exceptionally well, proving to be a vital player at several occasions. His first Serie A goal came during his second appearance against
Udinese on 2 September 2012, the end of the year came soon after and his goal tally stood at 4 goals on 14 appearances and 4 assists. On 9 January 2013 Vučinić scored in the 96th minute against
AC Milan to bring
Juventus to the semi-finals of
Coppa Italia where they will face
Lazio. The new year started very well for the Montenegrin, as he managed to score once again against Udinese. Vučinić gained notoriety on 5 April 2013 when after scoring a penalty kick goal against
Pescara, he
celebrated by taking off his shorts and was publicly seen in his briefs.
2013–14 season On 1 May 2014, in injury time of Juventus' Europa League semi-final elimination against
Benfica, Vučinić was sent off for a fight with opponent
Lazar Marković despite neither being on the field of play at the time, Marković having been substituted and Vučinić still on the substitutes bench.
Al Jazira On 4 July 2014, Vučinić joined
UAE Pro League side
Al Jazira for an undisclosed fee believed to be in the region of €6 million. He enjoyed a first season of individual success, scoring 27 goals in 24 matches and finishing as top scorer of the
league, but was troubled by injuries in the seasons following, amassing an additional nine appearances until his departure from the club in July 2017. ==International career==
