Injuries sustained whilst on international duty have accounted for three Arsenal players. William Gallas, Bacary Sagna and Nicklas Bendtner will all miss league and Champions League action during the coming week.
Boss Arsene Wenger told Arsenal TV Online: "Unfortunately we have lost some players over the 10 days - William Gallas, Bacary Sagna and Nicklas Bendtner. These are heavy losses and we have to compensate them.
"Fortunately the three of them don't look to be out for a long, long time but they will be out for the weekend game and I think the game on Tuesday.
"As well as them, Djourou got concussion during his game with Switzerland and will be assessed tomorrow to see if he is available. He does not look too bad and he could have a good chance to play.
"I am still waiting for Robin to come back so I don't know about him. However, he should be okay.
"He went with a muscle problem but he came on after 56 minutes last night and, from the reports I got, he should be all right. Both of them will be assessed.
"Also I am told Cesc has a broken nose. It should not stop him playing. He is here now and is being assessed."
One way the losses will be compensated for will be in the return of Frenchman Diaby.
"At least Abou Diaby is back in the squad again," Wenger said. "Even though he has not played games he will be used, at the least in the squad, because we have lost those three players."
