's Nick Teale uses the Bettorlogic form lab to assess this Saturday's game

Arsenal will be hoping that the international break doesn’t interrupt their flow of six consecutive victories when Birmingham City visit Emirates Stadium on Saturday. 

The Bettorlogic form lab suggests that Arsenal have fared well against promoted sides over the last five seasons. They have lost just four of 30 fixtures home and away, picking up an average of 2.27 points per game.

William Gallas is likely to start on Saturday and the stats indicate that his presence bolsters the Gunners’ defence. When he plays at Emirates Stadium against promoted sides, Arsenal concede an average of 0.67 goals per game - a 38% improvement on the team average of 1.07.

Looking at Birmingham, the stand-out stat is that they are yet to defeat a 'Big Four' club under the management of Alex McLeish, though there have only been six such games since he took charge in November 2007.

The Blues have played in three of the last five Premier League seasons and in that time have managed just a single away victory against the Big Four, a 1-0 win over Liverpool in November 2004.

However, in addition to that win they have managed four draws in 13 games - a sizeable feat for a club who have been relegated from the top flight twice in the last five years.

One final interesting note on Birmingham is the similarity of their Premier League record over the last five seasons (122 games) and their top-flight record under McLeish (32 games). There seems to be only a marginal improvement since the Scotsman took over from Steve Bruce almost two years ago.
