Laurent Koscielny (Arsenal)
A player who has really grown into a key player at Arsenal is French centre-back Laurent Koscielny. The 28-year-old first arrived at the Emirates Stadium as a relative unknown in 2010, having spent much of his career playing in the lower leagues of French football, though he has shown exceptional intelligence and reading of the game with some big-game performances for the Gunners. The likes of Bayern Munich and Barcelona have been linked with him in recent times, and it’s no surprise as Koscielny has proven to be yet another great find by Arsenal manager Arsene Wenger.
