Arsenal are in Manchester tonight looking to end their 12 year wait for a win at Old Trafford.
It was Sunday, September 2006 when Emmanuel Adebyaor - there's an answer for you - scored a winner with five minutes remaining in front of 75,595 fans.
Earlier in the game, United's debutant goalkeeper Tomasz Kuszczk saved a penalty and late on, the home side nearly pinched a win when Ole Gunnar Solkjaer saw his effort well saved.
Manchester United are unbeaten in their last 11 home league games against Arsenal, winning eight and drawing three.
Arsenal lost both Premier League meetings with Manchester United last season and their away record is especially poor. In fact, Arsenal have only scored more than once in three of their last 39 away league games against United. They've lost all three of those games.
It's unusual for these teams to meet in a midweek fixture. The last time it happened was in 2002 when Arsenal won 1-0 thanks to a goal from Sylvain Wiltord.
But Arsenal's dramatic win over Spurs on Sunday will give them plenty of hope against a United team that has had to come back from 2-0 down to draw 2-2 at Southampton. There will be plenty of focus on Pierre-Emerick Aubmeyang who has been in sensational form. He has scored with each of his last 10 shots on target in the Premier League.
We're going back to 2006 and asking you to try and name the Gunners line-up that day in our quiz.
