[1] Quick, versatile, and physically strong, Vučinić was known for his creativity, technique, and intelligence as a footballer, as well as his powerful striking ability from distance.

[7] 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.

[12] 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.

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.

[14] 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.

Arrival of new head coach Claudio Ranieri initially failed to change matters with the team continuing to slide down the standings.

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),[18] and then three days later in the Coppa Italia semi-final first leg versus Inter (Roma lost 1–0).

[21] 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 gained notoriety on 5 April when after scoring a penalty kick goal against Pescara, he celebrated by taking off his shorts and was publicly seen in his briefs.

[25] 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.

However, in September 2006 in a press conference in Rome, he said, according to La Gazzetta dello Sport "I am hundred percent Montenegrin and happy that the union with Serbia has ended".

[32] He scored the first goal of Montenegro's history when he netted a penalty kick in the team's first international match on 24 March 2007, a 2–1 friendly win against Hungary.

[3][36][37][38][39] Vučinić drew praise in the media for his vision, footballing intelligence, team play, and short passing accuracy, which allowed him to create chances for teammates and also made him an effective assist provider.

[3][45][46] Vučinić's work-rate in big matches was also brought into question at times with critics pointing to his "lazy" playing style, which often frustrated fans.
