Theo Walcott's slight hamstring problem should not prevent him from being available for Arsenal's FA Cup fifth-round tie against Leyton Orient on Sunday. Walcott sustained the injury in Wednesday night's 2-1 Champions League victory over Barcelona, but boss Arsene Wenger is confident the England winger will have recovered.
"We have a little concern about Walcott's hamstring but it should be all right," Wenger told Arsenal TV online.
Centre back Johan Djourou is sidelined for the trip to east London after suffering a back problem at the Emirates.
Right-back Bacary Sagna is available after being suspended against Barcelona but midfielder Abou Diaby is still banned.
"Djourou has a back problem. He is the one who certainly will not play on Sunday," said Wenger.
"All the others are smaller things I will assess slowly.
"Sagna is back from suspension but Abou Diaby is still suspended. Marouane Chamakh will be back in the group.
"There will be some rotation. We will see what I do. We play Sunday, Wednesday and then Sunday again.
"But I have shown in many competitions that I have the same belief in every player."
