wait..I'd like to see arteta on the bench. don't rate him.
Cazorla is best in an attacking midfield role where he doesn't have to track back phillip lahm or Alaba. Wilshere is better in a deeper midfield role IMO where he can glide past players and get the ball moving, which makes the best team to face bayern:
----------------------Scezny
---Sagna----Koscielny--------Vermalean---Gibbs
---------------Diaby-----------Wilshere
---------------------Cazorla
-------Walcott------Giroud-------Podolski
at least for me
