Arsenal's injury problems are showing no sign of ending.

The Gunners could be without Aaron Ramsey for about four weeks with a hamstring problem while defender Laurent Koscielny is also a concern with Achilles and calf problems.

Both players will definitely miss tomorrow's game against Newcastle, with Arsene Wenger facing into the game with just one fully-fit central defender available.

Right-back Mathieu Debuchy is likely to start centrally alongside Per Mertesacker.
