Arsenal enters the international break with significant injury concerns and a recent 3-0 defeat to Brighton, costing them their first-place position. Manager Mikel Arteta is managing the fitness of several players. Cristhian Mosquera, battling a muscular injury, traveled with the squad to Brighton but was not in the matchday squad; he is expected to be fit for the next game. Ben White, an English right-back, was also left out of the Brighton squad but is "all good" and rested, making him available for the upcoming match against Leeds United. The most significant setback is William Saliba, the French central defender, who is recovering from back surgery and will not feature again until November at the earliest. This extended absence poses a considerable challenge for Arsenal as they look to regain momentum after the break.
