Arsenal.com's Nick Teale uses the Bettorlogic form lab to analyse the statistics ahead of this Saturday's Premier League clash with Sunderland.
Arsenal have only lost twice to sides outside the 'Big Four' this season, but one of those defeats came away at this week's opponents, Sunderland.
However, the Black Cats approach the game in 13th place in the Premier League, and Arsène Wenger's side have a string of players who have never suffered defeat at home to sides in the bottom half of the table. Among them are Manuel Almunia (22 games), Bacary Sagna (21 games) and Denilson (15 games).
In fact, the Gunners' last defeat at home to a bottom-half team was back in April 2007, when West Ham became the first visitors to win at Emirates Stadium.
And this season, Arsène Wenger's side have been even better than average at home to teams occupying the bottom 10 Premier League places. The Gunners have scored 35 per cent more goals - 3.71 per game - and have picked up 2.71 points per game. The 2-2 draw at home to Everton is the only such match not won this term.
Striker Nicklas Bendtner has started five games for Arsenal at home to bottom-half clubs and the Gunners have kept clean sheets in all five. They have only conceded five goals in the 10 such games Alex Song has started. The Cameroon midfielder could return from injury against Sunderland on Saturday.
Since regaining promotion to the Premier League in 2007, Sunderland have struggled when visiting 'Big Four' clubs. They have picked up three points - all from draws - in 14 such games.
This season the Black Cats have picked up 26 points from 25 games. However, they have performed worse statistical without Lee Cattermole this term, and the young Englishman is suspended for Saturday's match at Emirates Stadium.
In the 13 games the midfielder has started this term, Sunderland have collected 19 points. In the 12 matches he has missed, they have picked up just seven points. Only one of their six League wins this campaign has been achieved without the 21-year-old. Steve Bruce's side also score 26 per cent more goals when Cattermole starts, and concede 18 per cent less.
