Arsene Wenger has given the following fitness updates ahead of Tuesday's Premier League game against West Ham.

on the team news...I cannot give you complete team news because many of them have to be checked today. We have plenty of uncertainties for muscular problems and fatigue. Who could be available who was not in the squad on Saturday? Maybe Rosicky and Koscielny - we'll have to test him definitely today. There are plenty of uncertainties so I have to make up my mind late on.

on the main uncertainties…The main uncertainties are Monreal who had to come off with a dead leg. Podolski had a little [muscle] problem but I think he will be alright. Then there is Oxlade-Chamberlain and Ramsey (both muscle tightness). They are the main problems.

on Koscielny's possible return…Koscielny will be tested today and I have to decide after training if I take the risk or not to start him tomorrow. on Jack Wilshere… Jack should start to jog this week. It is all going well, but we have to monitor him now day by day. I think the next three weeks will be very important for him.
