Arsenal face Gilberto absence

Length of absence
Gilberto did not travel with the Arsenal squad to Norway for tomorrow's UEFA Champions League match against Rosenborg BK and manager Arsène Wenger said: "We don't know how long for but it will be at least one month without any physical effort."

'Strange injury'
If Gilberto's absence is for a month, he will also miss the visit to Panathinaikos FC on 20 October. Wenger added: "It is a strange injury and an injury which usually concerns young players. I don't know if it is a recurrence of an injury he had when he was young. It could be a small fracture in one of his vertebrae."
