The Gunners possess tremendous depth in midfield, and after an injury-hit start to the season, the back four has been remarkably stable.
Still, Arsene Wenger will have to restock his side in January if he wants to make a serious push for the title in a race that seems to be more crowded than ever.
While it's still quite early for rumors to start flowing, let's look at who Wenger might have on his shopping list in a couple months.
Ideally, Arsenal would snap up Luis Suarez to supplement Olivier Giroud, but the chance of such a move coming off is about as likely as Arsene Wenger signing me to fill the void.
Jay Rodriguez, on the other hand, might be on the open market.
Rodriguez has contributed significantly to Southampton's outstanding start to the season, pitching in three goals and an assist in the Premier League.
The Daily Mirror reports that Arsenal have scouted Rodriguez for some time. Signing him would make sense, given that Olivier Giroud is the only legitimate option Arsenal have at striker. And no, I'm not including Nicklas Bendtner.
Many observers know that Arsenal attempted to sign Demba Ba on loan at the end of last summer’s transfer window.
He is still available, and Arsenal still have the same hole to fill.
Jose Mourinho was intent on keeping Ba in August, but the Senegalese has appeared only three times in the Premier League this season.
Ba is sufficiently skilled that he would be an excellent option late in games and could replace Olivier Giroud for a moderately long stretch if anything happened to the Frenchman. But he is not so outstanding that he would demand constant playing time and create unnecessary conflict within the squad.
Olivier Giroud might not be thrilled with this transfer, should it happen, but Robert Lewandowski would instantly make Arsenal’s attack among the best in the world.
Ordinarily, Lewandowski would be out of Arsenal’s price range. But because his contract expires at the end of this season, Borussia Dortmund will have little leverage in transfer negotiations.
Lewandowski is physically very similar to Giroud, and the two play similarly. One of the two would not get sufficient playing time, but the thought of the two in one team is mouth-watering.
Wojciech Szczesny’s excellent relationship with his countryman certainly couldn’t hurt the Gunners in a possible pursuit:
Marco Reus would be the ideal coup for Arsenal, despite the fact that he is cup-tied in the Champions League and would cost a pretty penny.
Arsenal have had some high-profile issues with release clauses in the recent past, but if reports like this in ESPN FC are correct, Reus could be had for slightly less than £30 million.
That would be a massive achievement for the Gunners, considering Reus’ extraordinary combination of pace, technical quality and goal-poaching ability.
For Arsenal, who are short on the wings and up front, Reus would be the perfect purchase.
