Arsène Wenger revealed the latest team news ahead of the Borussia Dortmund game:

on one new injury...
From Saturday everybody is available. We lost Tomas Rosicky in training, he has been replaced by Abou Diaby. Rosicky has a small thigh strain.

on Diaby’s return...
I am very happy. It's been a little bit quicker than expected because he looked good in training, so it's good to have him back. He has not played one minute since the start of the season and had his surgery in June, so it's good news to have him back.

on Van Persie...
Robin started on the bench last time [in the Champions League] because we had some medical concerns. Tomorrow we have no medical concerns at all, that means he will start.
