During his first season in Rome, he did not feature much as he had operations on his left knee twice. 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.
