#3 Winning the Premier League title at Old Trafford

Winning a title on the ground of your derby rivals is clearly one of the greatest feelings - as Arsenal did in 2004. But to win the title at the ground of the most dominant team in England, that is something else.
Arsenal vs Manchester United is a rivalry that defined the Premier League in the late '90s and early 2000s. They were the only two teams that won titles in that period and matches between them were always epic encounters.
However, in 2002, Manchester United were not in the title race. It was Sir Alex Ferguson's worst nightmare. Lose to their greatest rival in recent years or beat Arsenal and allow Liverpool to possibly clinch the title.
Ultimately, it was Sylvain Wiltord who settled the deal with a winner in the second half that effectively handed the title to Arsenal - who made absolutely no qualms about celebrating on the Old Trafford pitch after the game.
