Manchester United ruthlessly punished defensive errors to become the first side to win a league game at Arsenal since January in one of the games of the season so far.
Jose Mourinho's side were reduced to 10-men late on when Paul Pogba was sent off for a dangerous tackle and they were aided by a stunning goalkeeping display by David De Gea throughout.
But they did telling damage early on when Antonio Valencia pounced on a loose Laurent Koscielny pass to drill the opener, before Jesse Lingard side-footed a second after robbing Shokdran Mustafi to link smartly with Romelu Lukaku and Anthony Martial.
Pogba's dismissal arrived when he mistimed a tackle to effectively stamp on the back of Bellerin's leg, and the Frenchman will now miss the Manchester derby next Sunday.
But his moment of woe felt merely a footnote in riveting encounter which moved second-placed United to within five points of their city rivals.
