I feel things will be awkward with the Kroos signing, and even more so if they get James, I have no clue how they fit everyone in. Assuming all the rumours are true and they sell Khedira and Di Maria and sign Rodriguez, then I guess they should line up something like this:
---------------------Ronaldo/J. Rodriguez/Benzema------------------
----Ronaldo/J. Rodriguez------Kroos/Isco-----------Bale/Jese--------
-------------------Modric/Kroos-----------Alonso/Illarramendi--------
-----Marcelo---------Pepe------------Ramos-------------Carvajal----
--------------------------Iker/Lopez/Navas?-------------------------
To accommodate all of Ronaldo, Bale, and Rodriguez into the starting XI you would have to play one of them up top, either Ronaldo as a mobile striker or James as a false nine, because otherwise it's pretty much impossible to defend. Alonso or Illarramendi seem necessary because the Modric-Kroos pivot wouldn't hold up against strong teams. Against weaker ones however, they probably would be able to just outscore the opposition, and then play Rodriguez in the hole and Benzema up top. They would also have Isco from the bench who could either replace Kroos in the CAM role (in fact, I like Isco more there, but he's fallen out of favor recently), or he could even play farther back and give Modric some rest. They'll also have Jese, who can play on either wing or even up top, which will be great rotation wise. Real will have a lot of depth, for sure, but I feel like some players might be unhappy with playing time, and the midfield looks suspect, they really need to keep Khedira or sign someone else who is actually good at defending, since Alonso is old and Illarramendi is still raw. Still, it's a very interesting project.
