Juventus made it four wins out of four after keeper Gianluigi Buffon inspired them to a 2-0 victory over promoted Livorno in the Serie A on Saturday. Italy striker Vincenzo Iaquinta, who scored in Juve's 1-1 Champions League draw with Bordeaux in midweek, opened the scoring after eight minutes when he headed in Mauro Camoranesi's cross. Camoranesi was once again the provider as the Bianconeri doubled their lead on the half hour. The Italy winger midfielder released Claudio Marchisio with a deft pass to dink the ball over Livorno keeper. Buffon maintained his impressive displays to deny Livorno several goal-scoring opportunities. "Definitely it's a good period for me," the Italy guardian told Sky television after the match. "We've won fairly comfortably but Livorno had a good game. We move on with optimism, knowing we can improve." Juventus, who finished runners-up to Inter Milan last season, lead the Serie A table with a maximum 12 points. Juventus goals
