Arsenal.com's Nick Teale uses the Bettorlogic form lab to analyse the statistics ahead of this Saturday's Premier League clash with Birmingham

It has been suggested that Arsenal only have a couple of difficult games remaining in the Premier League title chase.
 
But try telling Chelsea and Manchester United that St Andrew's is an easy ground to visit.
 
Both have dropped points at Birmingham this season, and Arsenal will need to be at their best against one of the League's strongest defences if their title charge isn't to be derailed.
 
Alex McLeish's side are unbeaten in their last 11 home games, despite having taken on the Premier League's top two.
 
The Blues have kept clean sheets in 47 per cent of their home games this term - only Manchester United have conceded fewer League goals at home this season. The Red Devils have shipped nine goals at Old Trafford. Alex McLeish's side have let in just 10 goals at home.
 
This season Arsenal have scored more goals in the last 15 minutes of games than any other side, and Birmingham concede more goals after the 75th minute than any other 15-minute period in a game.
 
In addition to that, the Blues score more goals in the first 15 minutes of the second half than at any other stage of the game. That's the same period that Arsenal concede the least number of goals. The Gunners have been beaten just three times in the first 15 minutes after the break.
 
Nicklas Bendtner picked up an ankle injury in the win over West Ham last weekend but is expected to be fit to face Birmingham. The Dane spent a season on loan with the Midlanders three years ago and has an impressive record when facing mid-table clubs.
 
The 22-year-old has started seven times for Arsenal away at clubs in the middle third of the Premier League. The Gunners have collected an average of 2.57 points in those games - a 50 per cent improvement on the team average of 1.71 since the start of the 2004/05 season.
