Alumina suffered an ankle injury in last weekend's 4-0 rout of Blackburn but looks set to take his place against Newcastle on Saturday whilst former Manchester United man Silvestre will be ready for the clash at Emirates Stadium.
"Almunia could be back," Wenger told Arsenal TV Online.
"He had a good training session today so it looks like he will be available.
"Fabregas and Eduardo have come back into full training today but I think they will be short for Saturday.
"It is the first time back for Cesc. He is physically fit but he needs a few training sessions. So it will be after the international break for him.
"Silvestre is fit and available but Adebayor is not ready."
