Arsenal are keeping an eye on Bayern Munich striker Mario Mandzukic as they bid to strengthen their attacking options.
Mandzukic has bagged 10 goals in 16 Bundesliga outings so far this season, but it is understood a move for the Croatian is unlikely to materialise until the Summer.
The Gunners are now even more desperate to bolster their striking department with the news that Denmark international Nicklas Bendtner underwent a scan on Friday to determine whether he has torn or strained ligaments in his right ankle, and the full extent of the injury will be known in the next 24 hours.
If worse comes to worst, Wenger will be forced to act in this transfer window as he is already short of resources up front, and the worst case scenario is that Bendtner could be out for up to two months.
There are rumours that Arsenal have activated Diego Costa's release clause at Atletico Madrid, as well as rumours that they will move for Real Madrid's Alvaro Morata on loan.
There is also reason to believe they will move for Bayern Munich striker Mario Mandzukic but it is understood that could be a potential long-term move for the Gunners, such as this summer.
The Arsenal boss said: "My transfer plans depend on how long Bendtner will be out for.
"At the moment we are just considering our options. I must confess they are quite restricted. If it’s months rather than three weeks, then we would have to think about buying."
The Gunners could be left with only one fit striker when they host fierce North London rivals Tottenham Hotspur in the FA Cup Third Round on Saturday evening.
