The penultimate game of the season saw the Gunners travel to Old Trafford, with United needing a win to take the title race to the final day of the season.
Arsenal dominated the match from the start and just before the hour mark, Freddie Ljungberg's shot was slotted home with Sylvain Wiltord quickest to react to the rebound.
Sir Alex Ferguson showed admiration for Arsenal's powerful surge to the title.
"I certainly don't begrudge them their share of the honours because they play the game the right way."
