Arsène Wenger is waiting to find out the extent of Nicklas Bendtner's injury before deciding if he will dip into the transfer market.
The Danish forward, who scored a late goal in Arsenal's win over Cardiff City on New Year's Day, is due to have a scan on his ankle.
Wenger has said he is open to making additions this month if the right opportunities arise, but insists he is not in the market at the moment.
It is frustrating but you have to live with [Bendtner’s injury]Arsène Wenger
"I don't rule anything out but first I have to assess our internal situations with the injuries and the players coming back," he said. "We are just analysing the situation, being very cautious until we are well informed about Bendtner and [Yaya] Sanogo as well, because he is back in training now. We will make a decision after that.
"It is frustrating but you have to live with [Bendtner’s injury]. It is even more disappointing for him because he went through a tough time.
"He continued and was persistent in his attitude and just found back his real level. To be out straight away, I hope it will not be for a long time."
Fulham forward Dimitar Berbatov has been linked with a move to Emirates Stadium but Wenger insists he is not close to signing any player right now.
"He is not a name that we have considered at the moment,” he said. "We have not even been out on the transfer market, we have not contacted anybody.
"I don’t want to go into any speculation on any specific name because that would not help where the player plays at the moment and would be disrespectful to the player’s club. At the moment we are just considering our options. I must confess they are quite restricted."Copyright 2015 The Arsenal Football Club plc.
