The Gunners may be forced into action pending the results of Olivier Giroud's latest scan.
It is feared that Giroud could be out until the New Year after picking up an ankle injury in the 2-2 draw against Everton at Goodison Park.
Arsenal have been linked with Danny Welbeck, Loic Remy and Edinson Cavani, but Wenger has stressed that he won't resort to panic buying before the transfer window closes on Monday.
"We have plenty of players at centre forward. In England as soon as you have a problem, people want you to buy," Wenger said.

"Unfortunately, I can give you some clubs that every time they lose a game they say they might need to buy more.
"We are 24 hours from a big game and our focus is more on that than the transfer window.
"I've learnt one thing in our job - you say nothing categorically."
