Arsenal boss Arsene Wenger was reluctant to confirm he will buy in January after defeat to Chelsea.
Wenger has lost Robin van Persie for the season and is still waiting for Nicklas Bendtner to return.
"I believe I would rather have all of our players back," said Wenger. "I am not in a mood tonight to say straight away after the game that I would buy players. We have to deal with the disappointment, and respond to that massive disappointment we had today and try to win our next game. It's as simple as that."
