Arsenal manager Arsene Wenger has confirmed he could spend again before the transfer window closes.
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.
And if the right player becomes available, Wenger is not ruling out another plunge into the market.
He told arsenal.com: "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."
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.
"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."
An obvious target for Wenger would be a like-for-like replacement for defensive midfielder Song, who was a £15million departure.
Real Madrid's Nuri Sahin has been linked, as have Rennes midfielder Yann M'Vila and Sevilla winger Jesus Navas.
The Gunners head to Stoke on Sunday, when England midfielder Oxlade-Chamberlain is expected to be available following an ankle problem, but defender Laurent Koscielny (calf) is still not match fit.
