Arsène Wenger has revealed the following team news ahead of the Champions League game in Marseille:

on Olivier Giroud….
We have a few problems. Some with Ozil but the main one is Giroud, who has a knee problem. He will have a test tomorrow and hopefully he will be fit. But it will only be decided tomorrow.

on options up front if Giroud is ruled out…
I have not really thought about it that much but the obvious solution is Walcott. We’ll see.

on Per Mertesacker
There is good news. Mertesacker will be available again after illness.

on Mesut Ozil
He was ill and has some tight muscles after Saturday. But I think he will be OK. We are optimistic.
