#4 Laurent Koscielny – 31
After joining Arsenal from then newly promoted club Ligue 1 club, Lorient in 2010, the French defender has come leaps and bounds to establish himself as one of the best defenders in the Premier League. Having spent over six years with Arsenal FC, the Frenchman is one the longest serving players in the current Arsenal squad.
The 31-year-old is known to be an intelligent and proactive footballer who is quick and comfortable with the ball at his feet. He formed a solid partnership with German, Per Mertesacker, and in the current season, the French defender has a good partnership with summer signing Shkodran Mustafi at the back.
Koscielny is one of the most important players for Arsenal and has made nearly 280 appearances for them.
