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

on the latest team news...
Santos is out for 10 days with an abdominal strain. Oxlade-Chamberlain looks alright. Theo [Walcott] is out for Saturday, but has a chance for Wednesday at Everton.

on Abou Diaby...
If all goes well, three to four weeks.

on Tomas Rosicky...
He should be back with us on Monday. He started in team training on Monday. Last year from January to the end of the season he was one of the most influential players in our squad. I hope he can repeat that because until now we haven't seen him and he was injured at the European Championship. He has a similar injury to Scott Parker, they had operations at the same time and they will come back basically at the same time. It is very difficult [mentally] for him, because Tomas is a guy who loves to play, who is happy on a football pitch. When you have been injured as many times as he has been, it is not easy to take.
