SO Diaby is definitely out of tomorrow and the weekend, but Wenger isn't sure how much longer it will be than that. Vermaelen is also out tomorrow, could be back for the weekend.
Predicted team:
----------------Almunia--------------
--Sagna--Koscielny--Squillaci--Clichy--
-----------------Song----------------
----------Fabregas--Denilson----------
--Rosicky-------------------Arshavin--
---------------Chamakh---------------
Subs: Fabianski, Djourou, Eboue, Gibbs, Nasri, Wilshere, Vela
Nasri will hopefully see some good game time, he should be the first sub we use. Wenger will go with Denilson>Wilshere, though right now I think they are pretty evenly matched, Wenger will want Denilson's 'experience'. Koscielny will need to be on his toes, as Braga apparently have a very fast counter attack.
