There may also be further departures from the Emirates Stadium, the Frenchman said, prior to next Friday's 11pm deadline.
"I don't want make a promise that I cannot keep. It does not only depend on me. But there still could be some action on the transfer market - ins and outs," Wenger told arsenal.com.
So far Wenger has lost Robin van Persie to Manchester United and Alex Song to Barcelona, but he has also added Santi Cazorla, Lukas Podolski and Olivier Giroud to the ranks.
And if the right player becomes available, Wenger is not ruling out another plunge into the market.
He added: "We are working [in the market]. We'll see what we can do.
"The transfer market is open for two months and yet for one month and three weeks it is nearly closed. It wakes up completely in the last week and then every minute becomes important."
Wenger, whose side drew 0-0 at home with Sunderland on the opening day of the Barclays Premier League season, is happy with the state of his squad.
As he remarks, there could be a shuffling of some personnel in and out, but Wenger stresses there is no urgent need.
"We have a good, stable, focused squad. We just have to show how good we are in the season," he said.
