Arsenal could be without Mathieu Flamini against Borussia Dortmund after he took a knock to the head during the win over Norwich.
The French midfielder was suffering from concussion and had to be replaced in the 37th minute by Aaron Ramsey as the Gunners continued their fine start to the season against the Canaries.
Arsene Wenger is now waiting to discover the full extent of the concussion but says the player has to be rated as doubtful for the Champions League encounter.
"He had concussion," Wenger revealed. "He has double vision, so on the advice of the doctor I took him off because I did not want to take a gamble..
"I don't know if he will be available for Dortmund, it depends now what the doctors will decide. Sometimes they are not allowed to play for five days, it depends how big the concussion was."
