Cesc Fabregas is poised to return from injury as Arsenal host West Ham on Saturday.
Gunners captain Fabregas has been out since March 6 - missing the matches with Porto and Hull - due to a hamstring injury but should return after passing a fitness test.
Tomas Rosicky is also anticipated to be fit following a groin problem, but defender William Gallas has "an endless calf injury", according to Wenger.
Gallas has missed the last six games and is set to be out for at least two more matches - missing the Hammers contest and the match at Birmingham on March 27.
Alex Song will be back from a two-match suspension against the Hammers and Carlos Vela could be added to the squad as Arsenal seek to enhance their title bid after their last-gasp 2-1 win at Hull last weekend.
