And yes, that includes a striker.
Considering the improvements of players like Giroud and Aaron Ramsey, as well as the first-team players soon returning from injury such as Theo Walcott, Lukas Podolski, and Alex Oxlade-Chamberlain, Wenger believes that he might not need to buy any players in January.
"We are not desperate to sign anyone in January. If there is a good opportunity, then why not? But at the moment, when you know who is out and that they will come back in November and the beginning of December, then you have a really massive squad."
Even though Nicklas Bendtner is our only other recognized striker beside Giroud, we will soon have Podolski and Walcott returning. Given the inflated market prices for strikers recently, and the historical inflation of prices for strikers during the January transfer window (Fernando Torres and Andy Carroll come to mind), it's doubtful that Arsenal could find any "good opportunities" during the winter window that are better than what we have in Podolski, Walcott, and yes, even Bendtner.
On the other hand, in January, a certain Polish striker will have only 6 months left on his contract... and a certain club might be willing to sell to any club that doesn't rhyme with Mayern Bunich...
"I will be able to sign a contract in January, but I have never said that I will sign a contract with [name redacted]...One day I would like to play in Premier League. It would be a great experience."
