Laurent Koscielny may be turning 30 - but he insists he still feels like a young man.
The defender has firmly established himself as one of the best centre backs in the Premier League since his arrival at the club in 2010.
However, Koscielny recognises that he now must put extra effort in during training to prolong his career.
“Footballer or not, after 30 is a big part of your life,” he told Arsenal Player. “For a footballer it is important as you are closer to the end of your career than you are to the start. But, I feel like a young man.
