Olivier Giroud underwent surgery on an injured tibia and will be out for the remainder of the calendar year.
"Olivier Giroud had surgery today. It went well but he will be out, for maybe top competition, until end of December or beginning of January," Wenger told Sky Sports News.
Giroud suffered a small fracture near his ankle after the ball smashed into the sole of his boot, forcing his foot towards his shin in Saturday's match against Everton.
"We will look around but we want quality. We have quality, we have Walcott coming back soon, Podolski, Campbell, Sanogo. To find players better than we have would be very difficult," said Wenger about the prospect of finding a replacement for Giroud.
