Arsenal v Olympiacos preview
Team news ahead of Wednesday night's Champions League Group B clash between Arsenal and Olympiacos at Emirates Stadium.
Arsenal midfielder Abou Diaby has been ruled out of action for three weeks with a thigh injury, so is a definite non-starter against the Greek champions.
Diaby suffered the injury attempting a shot at goal in the Gunners' 2-1 defeat against Chelsea on Saturday.
The 26-year-old adds to Arsenal boss Arsene Wenger's injury worries, with the Frenchman already sweating on the fitness of Mikel Arteta and without Wojciech Szczesny for a further few weeks, while midfielder Tomas Rosicky and right-back Bacary Sagna remain sidelined.
Speaking in the build-up to the game, Wenger said: "Arteta will have a test (on Wednesday) on an ankle injury. Diaby is out with a thigh injury.
"We are pleased with (Jack) Wilshere, but we will take it slowly. He is exceptionally happy. (Wojciech) Szczesny will be two or three weeks still."
