From what ive seen and with the inclusion of Varane now i think it will look something like
----------------Diego Lopez
---Arbeloa----Pepe---Varane--Marcelo
-----------Khedira-----Illarramendi
------Bale----------Isco--------Ronaldo
------------------Benzema
It will look something like this. Benzema will drop deeper and allow bale and ronaldo to go forward as cfs and isco will sometimes drop deeper
Yes but I think di maria will start ahead of bale because madrid wants to rest bale for the clasico on the weekend and he's still not fully fit. If di maria plays, he will help with madrid's defence as always and track back to help out arbeloa, did you see their formation against Galatasaray? It was like di maria was playing as a deeper right midfielder behind ronaldo and isco in a formation that looks like this
-------------------Casillas------------
Carvajal-----Ramos----Pepe---Marcelo
Di Maria-----Modric----Khedira-------
---------------------Isco--------Ronaldo
------------------Benzema-------------
As for how they play, Ancelotti has stated that he intends to make Madrid play possession attacking football and says that they won't base their tactics entirely on counter-attacking as Mourinho did. I have also noted that they play much less long balls and tend to pass shorter looking for openings and crosses.
As for team selection, Ancelotti said that Lopez will be his league keeper and Casillas will be his CL keeper so obviously he'll play Casillas against us
