Arsenal's injury crisis has worsened after Alex Song was ruled out of Tuesday's Champions League game against Barcelona with a groin injury.
The Cameroon international limped out of Saturday's 1-0 Premier League victory over Wolves with the problem and has now joined a lengthy list of absentees for the second leg of a Champions League quarter-final at the Camp Nou.
The tie is poised on a knife-edge at 2-2 after last week's first leg stalemate but manager Arsene Wenger has seen his squad decimated by injury during the past few days.
Captain Cesc Fabregas (broken leg), William Gallas and Andrey Arshavin (both calf) were all injured during the first leg.
Robin van Persie, Aaron Ramsey and Kieran Gibbs were all already ruled out with long-term injuries.
Speaking about his mounting injury crisis before Song was ruled out, Wenger explained: "The problem we have at the moment is that we are short.
"We rested (Abou) Diaby, (Gael) Clichy, (Samir) Nasri and (Nicklas) Bendtner against Wolves and we have Fabregas, Gallas, van Persie, Arshavin out.
"Can you believe that? That's eight players. Any injury now can hit us very hard."
