Laurent Koscielny has been a regular in Arsenal's defence for the past two seasons
Arsenal defender Laurent Koscielny has agreed to sign a new long-term deal at The Emirates.
The 26-year-old Frenchman moved to north London from Lorient in July 2010 and has made 63 Barclays Premier League appearances in his two seasons to date with Arsene Wenger's side.
The France international has also scored some vital goals, including the winner in the 3-2 win over West Bromwich Albion on the final day of the 2011/12 season - a goal which ensured the Gunners qualified for the UEFA Champions League.
"The development that he has shown has been absolutely exceptional"
- Arsene Wenger
Koscielny told Arsenal's website: "I'm delighted to have reached agreement with the club.
"I have had a fantastic time here and look forward to an exciting future with Arsenal."
Arsenal manager Arsene Wenger said: "Laurent has been outstanding for us over the last two seasons.
"When you consider that until 2009 he was playing in Ligue 2 in France and that he is now performing at the very top level in the Premier League and for his country, the development that he has shown has been absolutely exceptional.
"Laurent is a top-class player and I am very pleased he has decided to commit his future to the club."
Koscielny has also won four caps for France and played the full 90 minutes as they lost to Spain in the quarter-finals of UEFA EURO 2012 in June.
