Arsène Wenger has revealed the following team news ahead of the Wolves game:

on the team news...
Gibbs is out with a fatigue of his groin, so Santos is back. Koscielny is of course suspended for two games and Gervinho is ruled out with an ankle problem. Squillaci and Park come in. The squad is quite easy to pick because all the players available are in.
 
on Gibbs...
Gibbs is short-term, it is more fatigue than an injury. Santos comes straight back.
 
on Gervinho...
He is short-term as well. He had a test today which was not completely satisfying but he is not far.
 
on reports Per Mertesacker had started training...
No, no, no, he is still in Germany for his rehab and he is starting his running but he is not back in training. He is fine though.
