The return of Mathieu Flamini to the Emirates Stadium on Thursday marked only the second signing Wenger has made since the end of last season amid calls from supporters for the Frenchman to spend big as the transfer window prepares to close on Monday.
With Arsenal set to take their place in the UEFA Champions League group stage for the 16th successive season, concerns have been raised that Arsenal may not have strength in depth to compete in four competitions.
"I am confident (of bringing players in)," he said ahead of Arsenal's Premier League derby with Tottenham on Sunday. "We will not panic buy, that is for sure. It is not my strength to panic.
"The players we have here know how he want to play. That is important. I don't think that prices are linked with (the) quality of players.
"It has a negative impact when you lose your best players. We have gone through that consistently."
"The chance for him to leave now is very small," the Frenchman added. "If he comes back well and gets fit, I will use him"
