Arsene Wenger admits Arsenal are cautiously taking things "day by day" as they look to get captain Cesc Fabregas fit for next week's Champions League trip to Barcelona.
The Spain World Cup winner limped out of the Barclays Premier League game against Stoke last Wednesday night with a hamstring problem, and missed the shock Carling Cup final defeat to Birmingham as a result.
Wenger remains optimistic the Gunners' skipper can recover in time to face his boyhood club at the Nou Camp, where Arsenal will hold a slender 2-1 lead. Wenger told Arsenal TV Online: "As for Cesc, we go day-by-day. We assessed him on Thursday and he is positive about his injury."
"We feel he has a chance. I do not want to disappoint people so I say he has 'a chance', I strongly believe that."
Arsenal are already without striker Robin van Persie and England winger Theo Walcott, while midfielder Alex Song is struggling to shake off his knee problem.
"Alex Song is out on Saturday and he is doubtful for Barcelona," Wenger confirmed.
"At the moment he has not practiced at all. He has this knee problem that gets better everyday, but we'll assess it on Monday."
Tomas Rosicky is expected to be okay after having to go off in Wednesday's 5-0 FA Cup fifth-round replay win over Leyton Orient following a blow to his head.
