A double from French forward Samir Nasri condemned United to a second defeat of the season, and moved Arsenal ahead of the champions in the Premier League table.
The Gunners' summer signing from Marseille struck with 20-yard efforts in either half, while United had only Rafael's late consolation to show after passing up a string of chances. Wayne Rooney, Anderson, Cristiano Ronaldo and Ji-sung Park were all unable to find a way past Manuel Almunia, while Gael Clichy was a touch fortunate to survive a first-half penalty claim for handball.In the final minute of normal time, Silvestre headed Giggs' cross clear as far as the edge of his own area, where Rafael took a touch on his chest and lashed a stunning left-footed volley past substitute goalkeeper Fabianski, who had earlier replaced the injured Almunia.
