Wenger revealed on Danny Welbeck, who has been back in training since last month, is in contention to figure in the third-round tie at Preston.
The England Striker will only start on the substitutes’ bench, but his return is a major boost for Arsenal.
Arsenal Manager said: “I haven’t decided yet with him. He could play but it depends on Lucas Perez a little bit. He injured his ankle.
“It also depends on how Danny feels. Physically his fitness it at quite a good level but of course the ideal way is to give him two or three games with the Under-23s.
“But the situation is not always ideal, sometimes you have to hurry up.”
