Arsene Wenger gave out all the team & injury updates on Arsenal.Com:
About 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].”
“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.”
“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.”
“Ryo has a hamstring problem that he got from the Norwich game, he will be out for Saturday.”
Chamberlain, Sanogo, and Diaby are the long-term absentees.
Arsenal’s biggest boost will be the availability of Theo Walcott again. On his day, English winger can be devastating to the defenders, using his express speed and acceleration. Beware Southampton, your own youth product is back to hurt you.
