The Gunners are already missing defenders Thomas Vermaelen, Johan Djourou, Sebastien Squillaci and Laurent Koscielny through injury, and this latest blow will indeed stretch Arsene Wenger’s squad to the limits.
The injury was confirmed by the French Football Federation and the 28-year-old will be out of action until the new year.
The French Football Federation statement read: “The doctor of the France team, Fabrice Bryand, was informed by Arsenal of a fracture to the right fibula of Bacary Sagna.
“The player (Baccary Sagna) was hurt during the match lost 2-1 by his club against Tottenham on Sunday. The defender will be operated on and is not expected to be available for at least three months.”
