Arsenal must negotiate a tough Champions League trip to Porto without a number of first-team regulars.
Andrey Arshavin and Alex Song picked up injuries during last week's win over Liverpool and they have not recovered in time for the first leg against the Portuguese champions. What's more, they have been joined on the sidelines by William Gallas and Manuel Almunia. Meanwhile Eduardo, tipped for a return on Wednesday night, is still unavailable.
Arsène Wenger ran through his list of walking wounded before his 18-man squad boarded their flight to Portugal on Tuesday afternoon.
"William Gallas has a calf injury. Alex Song has a knee injury. Andrey Arshavin has a hamstring injury," said Wenger.
"Manuel Almunia has a finger injury, and the hand is quite useful for goalkeepers. He had already a twisted finger and he made it worse and I didn’t want to take a gamble on it. Eduardo has a recurrence of his hamstring injury."
Long-term absentees Robin van Persie, Kieran Gibbs and Johan Djourou are also absent but Carlos Vela returns from a knee injury.
