I've been using this formation in countless games for years. I built it around Dennis Bergkamp and Patrick Vieira. Although neither are at Arsenal now, I still stick to the formation.
----------GK---------
-------CB----CB------
--RB--------------LB--
----------DMF--------
----RMF--------LMF---
----------------------
----------SS---------
-------CF----CF------
My usual options (in order of preference):
GK - Lehmann
RB - Eboue, Hoyte
LB - Clichy, Gallas, Hoyte, Flamini
CB - Toure, Gallas, Senderos
DMF - Gilberto, Toure, Flamini, Fabregas
RMF - Fabregas, Ljungberg, Hleb
LMF - Rosicky, Walcott, Ljungberg
SS - Hleb, Baptista, van Persie
CF - Henry, van Persie, Adebayor.
Being an Arsenal fan, I know these players well. My options are quite endless. I experimented with Toure in the DMF role a few times, and he did a good job in both occasions.
