Arsenal defender Laurent Koscielny earned an unwanted record in Arsenal’s 1-0 defeat at Stoke City in the Premier League this afternoon. In conceding the winning penalty with a reportedly dubious handball, Koscielny has now conceded six spot-kicks since his arrival at the Emirates in 2010.googletag.cmd.push(function() { googletag.display(“div-gpt-ad-1389116196215-0”); });According to stats from Opta, no other player has conceded more Premier League penalties in this time. The defeat leaves Arsenal four points behind Chelsea in this season’s title race, with the Gunners facing trips to Stamford Bridge and Tottenham’s White Hart Lane, as well as a home tie with Manchester City later this month. Frenchman Koscielny was signed by Arsene Wenger for 9.7 million from Lorient four years ago and he has forged a successful defensive partnership with Per Mertesacker. In his time as an Arsenal player, he has been red-carded four times, including twice in matches on the opening day of the season.
