Manchester United host Arsenal this Saturday lunch time in the Premier League.
The game between these two sides was, for many years, THE big match of the season as they battled it out between them for the title in the late nineties and early 2000s, before Chelsea and then Manchester City upset the duopoly with their pots of cash.

Now is your chance to prove it in our picture quiz.
Anyone who doesn't get 11/11 can see Roy Keane after school.
