Smash and grab by United today. Arsenal were dominant throughout, with a hat-full of chances in both halves but a combination of brilliant goalkeeping by De Gea and poor finishing kept United in the game.
At the other end, United had no such problems, clinically snatching two second-half goals to record their first away win of the season. A late goal by Giroud was too little too late for Arsenal.
Big result for United which moves them above Arsenal into fourth.
