Arsenal midfielder Abou Diaby has been ruled out for three weeks with a thigh injury.
The 26-year-old adds to Arsene Wenger's injury worries, with the Frenchman sweating on the fitness of Mikel Arteta and without Wojciech Szczesny for a further few weeks.
"Arteta will have a test tomorrow on an ankle injury. Diaby is out with a thigh injury.
"Szczesny will be two or three weeks still."
