Arsenal manager Arsene Wenger has hinted that the club could make a move in the January transfer window if their form takes a further hit between now the new year.
The Gunners beat Sunderland on Sunday, just their third league win of the season, maintaining their 10th spot in the Barclays Premier League.
And Wenger says if Arsenal's disappointing form continues, the club may be forced to act from the January transfer window.
"But, firstly, it depends who is in the market and, secondly, it depends how well we do from now on to December. Because if we have good results and the players develop well, number wise we have a big squad."
"Many times people judge your buys quickly but I'm quite happy with the buys we made," Wenger added.
"I'm not happy with our results, but that's completely different. I've heard [Alex] Song is a bad buy, [Thierry] Henry was a bad buy.
"Andre Santos was not ready physically when he came but I think he's a very good player. Arteta is a very good player. Mertesacker is getting stronger. They basically all arrived one month ago. What is at stake is to rebuild the team."
Arsenal have been linked with moves for Yann M'Vila and Moussa Sow in the winter and are reportedly ready to dive into the market once more.
The club made five frantic signings during the back end of the transfer window, and Arsenal's wretched start to the season could see further signings.
