Walcott has been out of action since November when he dislocated his shoulder whilst playing for England and Eduardo has managed one match since breaking his leg last year but has experienced hamstring troubles since his two-goal return.
"I will see how they (Walcott and Eduardo) look tomorrow and Saturday but they will certainly be in the squad, especially Theo," Wenger told Arsenal TV Online.
"We have to wait and see how Eduardo reacts and responds to his injury."
Wenger also commented on the fitness of African stars Kolo Toure and Emmanuel Adebayor.
"We are quite optimistic about Kolo but we have to assess the situation today completely,” he added.
“I don't think I will involve him on Sunday. But Gallas should be back for Sunday and it looks to be like Kolo will be back for next week [against Roma].
"Adebayor is definitely out for Sunday and for Roma too."
