There may also be further departures from the Emirates Stadium, the Frenchman said, prior to next Friday's 11pm deadline.
Wenger has lost Robin van Persie to Manchester United and Alex Song to Barcelona, but he has added Santi Cazorla, Lukas Podolski and Olivier Giroud to the ranks.
If the right player becomes available, Wenger is not ruling out another plunge into the market. And we all know of his interest in the Newcastle midfielder.
Wenger: "Some things can still happen.
"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.
"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.
"Everybody has played for time for seven or eight weeks and now suddenly everyone is in a hurry. And that is when the most intense activity happens."
