Two Arsenal stars currently hold a defensive record that shouldn't be boasted about.
The Gunners slumped to a 2-0 defeat at the hands of table-toppers Chelsea yesterday as an Eden Hazard penalty and Diego Costa goal were enough to secure the points for Jose Mourinho's team.
It was not a terrible performance from Wenger's team - they were just undone by two moments of brilliance from their opponents.
Hazard won a penalty off Laurent Koscielny for the first goal and Francesc Fabregas laid on a sublime pass for Diego Costa to score the Blues' second.
However it's the first goal that highlights a problem Arsenal has suffered in recent years. Since 2010 both Koscielny and Wojciech Szczesny have conceded the most penalties in the Premier League.
Before yesterday's clash with Chelsea, Koscielny was joint first with his goalkeeping team-mate for most penalties conceded, but now unfortunately for him he had pulled ahead with seven penalties conceded since August 2010.
Szczesny is now second on six and then Sebatian Bassong, Martin Skrtel and Ryan Shawcross follow with five each. The majority of the time giving a penalty away is very costly, and penalties that both the Arsenal men have conceded in recent times have in fact proven to be so.
It should be a worry to Arsenal and Wenger because it gives opposition attackers that extra impetus to take a chance and run at the defence, just because they know the likes of Koscielny or Szczesny could potentially make a rash challenge.
Neither of the Arsenal pair are bad players, nor do they look out of place in the Arsenal squad, but clearly they are making challenges or finding themselves in positions where there is a great risk of giving away a penalty. If the Gunners are going to challenge for trophies and titles this season, and in seasons to come, then they need to cut out errors that lead to needless penalties.
