's Nick Teale uses the Bettorlogic Form Lab to analyse the statistics ahead of Sunday's Premier League clash with Manchester United at Emirates Stadium.

Manchester United are currently one point ahead of Arsenal in the Premier League title race. But Sir Alex Ferguson's side have found points hard to come by on recent visits to 'Big Four' grounds.
The Premier League champions are yet to register a League victory over Arsenal at Emirates Stadium, and have collected just one point from six games away at 'Big Four' clubs since beating Liverpool 2-0 at Anfield in December 2007.
Since the start of the 2004/05 season, United have picked up 17 points in as many games at 'Big Four' grounds, while Arsenal have collected 23 points from 16 matches at home to fellow 'Big Four' sides.
Ferguson's side have also struggled for goals in those games, scoring an average of 0.82 per game, a significant dip on the average on 1.94 goals in all League games over the same time span.
Of United's last 50 games, Gary Neville has only played in just 11. But United have won them all.
They've also lost just four of the 42 games Dimitar Berbatov has started since joining the club on the final day of the summer transfer window in 2008. Of the 17 games he has missed, United have won just nine, scoring 1.53 goals per game compared with 2.21 when he does start.
Gael Clichy has started seven times for Arsenal at home to 'Big Four' opposition, and the stats show that Arsenal have conceded 43 per cent fewer goals in those game compared to the team's average since the summer of 2004.

As a result, Arsenal have also picked up 43 per cent more points with the French full back in the starting XI.
