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

on Theo Walcott....
Theo will be back for Saturday in the squad. He's completely fit again. He has not played for a long time, of course, he has not played even a reserve team game, but I will put him in the squad on Saturday. Yes [I will use him cautiously].

on Mathieu Flamini... 
He is suspended.  

on Tomas Rosicky...
Tomas was ill, he had one or two [normal] training days, he could be in the squad as well on Saturday. We have a final test on Friday.

on Lukas Podolski...
Podolski is not too far away, I would say three weeks. He is doing fitness training on the pitch. He starts to do some ball work too, he still needs two or three weeks before we see him on the pitch for Arsenal.

on Ryo
Ryo has a hamstring problem that he got from the Norwich game, he will be out for Saturday.

on the longer-term injuries...
Chamberlain is at least one month, Sanogo is January, Diaby will be March.
