Arsenal manager Arsène Wenger defiant in face of criticism and vows to put things right, starting at Reading Arsenal should have striker Olivier Giroud in contention again following a back problem, while defender Laurent Koscielny has resumed training after his thigh injury. England winger Theo Walcott (calf) continues to be assessed. Wenger, meanwhile, has reported "slow progress" on the recovery of France midfielder Abou Diaby, who has been sidelined by a muscular problem since the end of September. "I cannot give you any fixed date because we are a bit in no-man's-land on that front," said the Arsenal manager. He is working, but we are waiting for him to come back. He is not ready.
