Arsenal central defender Laurent Koscielny is looking forward to locking horns with his former team-mate Robin van Persie at the Emirates Stadium on Sunday.
Koscielny added: "Per is a very good player. He reads the ball well. He is clever, attacks the ball and wins headers whereas I can go behind and be quick and cope with the long balls. "He is good technically so he is good for the defence. Per is calm on the pitch. "He is good for me, he uses his experience, this helps me, and he helps the team."
