Having lost both Robin van Persie and Alex Song this summer and brought in Santi Cazorla, Lukas Podolski and Olivier Giroud, Wenger is thought to be keen to add another midfielder and defender to his squad this summer and has refused to rule out any late action.
"Some things can still happen," Wenger told the club's official website. "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."
Despite suggesting there will be more business for his side in the transfer market before the end of the month, Wenger said he was generally happy with the state of his squad.
"We have a good, stable, focused squad. We just have to show how good we are in the season," he said. "We have Abou Diaby and Alex Oxlade-Chamberlain back now while Tomas Rosicky and Jack Wilshere are coming back.
"They are all international-stature players. I focus highly on that. If we get these players back in good shape then we have a very, very strong squad."
