Arsenal may trail Manchester City on just goal difference but are still sorely in need of a striker if they are to end their 12-year wait for the Premier League title.
The Gunners have largely relied on the form of Mesut Ozil and Alexis Sanchez this term and their shortages up front could hamper their chances of landing silverware when the season ends in May.
With the January transfer window edging closer, Wenger may have to delve into Arsenal's transfer fund, even though Danny Welbeck is due to return to action in the New Year.

After finishing third last year many expected Wenger to splash the cash in the summer, but the window slammed shut, leaving the Gunners as the only side in Europe’s top five leagues not to sign an outfield player.
Veteran goalkeeper Petr Cech was certainly an impressive addition, but as the only arrival at the Emirates Stadium, the angst amongst fans was almost tangible.
Towards the latter weeks of the summer, Karim Benzema emerged as their chief target, but the Frenchman instead decided to remain at Real Madrid after the appointment of Rafa Benitez as manager.
Arsenal have endured contrasting fortunes when spending money in January, with the likes of Gabriel, Andrey Arshavin and Nacho Monreal all arriving at the mid-season point. However, given the strength in depth of their title rivals, it seems a move for a new forward should be a given.
Southampton star Saido Mane is tickling the fancy of Louis van Gaal at Manchester United, but his combination of speed and potency would make him a key signing for Arsenal instead.
And they may also be given more hope in a renewed pursuit of Benzema, with the 27-year-old currently embroiled in a scandal over a sex-tape of teammate Mathieu Valbuena.
Theo Walcott and Olivier Giroud have both fared admirably up front, but neither possesses the required calibre to help Wenger end his wait for the league crown.
Manchester City are sitting pretty at the summit despite the absence of Sergio Aguero with Wilfried Bony carrying the mantle in the absence of the Argentine.
Close on their heels lies Manchester United. They invested heavily in Anthony Martial this summer and he has proved a useful addition. They also have Wayne Rooney, who, despite his poor form, has the potential to make a significant contribution.
Even Tottenham and Liverpool have Harry Kane and Christian Benteke, and the strength of Arsenal’s rivals highlights what they need to do to win the country’s biggest domestic gong.
