Arsenal v Tottenham combined XI: north London derby’s best team ahead of FA Cup clash

Laurent Koscielny (Arsenal)

Laurent Koscielny is the perfect partner for Per Mertesacker, possessing pace and excellent man marking ability.

He might be prone to the odd gaffe, and has given away a few distinctly avoidable penalties in his time, but when at his best, Koscielny has kept the very best strikers in the world quiet.
