Belletti's first and only goal with Barcelona was the winner in the 2006 UEFA Champions League Final. On 17 May 2006 at the Stade de France in Paris, Barcelona played English club Arsenal, Oleguer started over Belletti, who was on the substitute bench. When manager Frank Rijkaard eventually brought him on for Oleguer, Belletti scored the second goal in a 2–1 come-from-behind win to give Barça the Champions League crown.
