Substitute Adriano fired a dramatic 82nd-minute winner as Brazil's Internacional beat hot favourites Barcelona 1-0 to lift the Club World Cup on Sunday.
European champions Barcelona had totally dominated in Yokohama until Adriano latched on to Iarley's clever ball to poke the ball past goalkeeper Victor Valdes.
Deco forced a superb save from Inter goalkeeper Clemer moments later and Ronaldinho shaved the post with a free kick from 25 metres in the 85th minute as Barca tried to respond.
Barcelona struggled to reproduce the same form that they showed in their 4-0 demolition of Mexico's America 4-0 in the semi-finals.
But Inter, who scraped past Egypt's Al Ahli 2-1 in their semi-final, rarely threatened and Adriano's winner was a bolt from the blue.
Inter's victory made it two wins out of two for Brazilian teams in the revamped FIFA tournament involving the world's six continental champions.
Sao Paulo beat Liverpool 1-0 in last year's final.
