Manchester United won a tight game between the two clubs in November.
United visited the Emirates in November, recording an impressive 2-1 win in what was Louis van Gaal's first away win in English football.
That result helped spark an impressive run, coming after a win over Crystal Palace that started a six-game winning streak, and with the Red Devils avoiding defeat until a loss to Southampton in January.
The November defeat meant Arsenal lost two in a row after a reversal at Swansea, and saw renewed calls for Arsene Wenger's dismissal among some fans. But since then, barring a couple of defeats, the Gunners have put together a strong run that sees them now up to third place in the Premier League.
Below, we look at the records and points accumulation of the two teams since their November meeting:
Arsenal - 22 games played - 17 wins - 4 losses - 1 draw - 47 goals scored / 20 conceded - 37 Premier League points
Man United - 20 games played - 13 wins - 2 losses - 5 draws - 36 goals scored / 12 conceded - 34 Premier League points
Though of course the figures above are only relate to the teams each side has faced in that time, they do tend to suggest that Arsenal have been more clinical at dispatching their opponents in the fixtures since the 2-1 victory, with a strong win ratio and an impressive goal difference.
United, on the other hand, have failed to record as many wins as they would have liked, even though they have fewer losses than their London rivals and also boast an improving defensive record.
It looks like Arsenal just edge United on the form stakes with the FA Cup game just three days away, but with Louis van Gaal's side difficult to beat, it promises to be a fascinating contest as Arsenal look to repay United for that November defeat.
