Arsenal's Podolski, Walcott out of West Brom fixture
The German striker has a slight hamstring strain and will miss the visit of the Baggies to the Emirates Stadium on Saturday.
"From Tuesday night in Greece (against Olympiakos) there are no new injuries so we have a selection from the combined squad of Tuesday and Saturday," Wenger told the club's official website.
"Podolski's injury is a hamstring. It should be short-term."
