Arsène Wenger revealed the following team news ahead of Tuesday's game against Borussia Dortmund:

on Mathieu Flamini...
He is doing well. He has practised normally but we will not play him because there is a five-day rule that we will respect. We will not to take any chances. It was a concussion and the doctor advised us not to play him. He will be OK for the weekend.

on other changes and possible rotation...
A little bit yes, certainly, but I leave myself 24 hours until tomorrow [Tuesday] afternoon to decide that.
