In what has been the closest title race since the 1980s the Gunners have taken advantage of Manchester United's lapses and it looks like they have developed a system that works for them. United might still be the top passers and the most prolific goalscorers but Arsenal have the points and that's what really counts.
Against Tottenham, the odds are greatly in the home side's favour and when it comes to shooting, the Gunners' aim has been true. With 50% of their shots hitting the target, there is no side in the top flight that are more accurate with their efforts than Arsene Wenger's side. Conversely, the crowd at White Hart Lane have had to deal with more of Tottenham's shots than the opposing goalkeepers have. With just 38% of Spurs' efforts hitting the target they are the most inaccurate side in the Premiership.
The visitors might also struggle to keep the ball for significant periods of time as only Manchester United can better Arsenal's 78% pass completion rate. Tottenham - who pride themselves on their passing - have completed 74% of their distribution.
If Tottenham are going to get something from this game then their 5-3-2 formation could well be the answer. The wing-back system allows them to push on up the flanks and only one side can better their 28% cross completion rate.
The one player who been centring the ball especially well is Darren Anderton. He has whipped in 73 accurate crosses this season and only David Beckham, Nolberto Solano and Laurent Robert can better that.
This game could see Arsenal move a step nearer to the title, but north-London derbies are not the most predictable of games - for Tottenham and their fans, a famous win at the home of their local rivals could be a smug end-of-season-reward.
