In this thread, we will compare both Real Madrid and Barcelona starting XI to chose the player we think are best over that of the other team.
Here are the predicted line-up for each team:
Navas - Ter Stegen
Marcelo - Alba
Ramos - Pique
Pepe - Mascherano
Carvajal - Vidal
Casemiro - Busquets
Modric - Rakitic
Kroos - Iniesta
Bale - Messi
Ronaldo - Neymar
Benzema - Suarez

From this predicted line-up, create the team who you think would be best or the one who you think would be the most enjoyable to watch.

Navas
Marcelo - Ramos - Pepe - Carvajal
Busquets
Modric - Ineista
Messi - Suarez - Ronaldo

There is no way Madrid are better along their entire backline than Barca, but I can't really find a way around that.

Navas
Marcelo, Piqué, Pepe, Carvajal
Busquets, Modric, Iniesta
Messi, Ronaldo, Suárez

I would include Sergi Roberto in the team rather than Carvajal. Why isn't he on the list, and why is Vidal there?

Navas
Carvajal-ramos-varane-marcelo
Busquets-modric-iniesta
Messi-suarez-neymar

@phenohyte Well, I wasn't sure who to put on the Barca side between Sergi Roberto and Aleix Vidal, but I thought it made more sense to put a player who was really more at his place at the RB position. Sergi is more of a jack of all trade but if everyone think he deserve to be there above Vidal, tell me.

@liomessi10 You were suppose to take player that were in the list I putted you know... But I don't want to control anybody so if you prefer putting Varane, do it, its fine.

Here is my team:

----------------Navas---------------
Marcelo-Piqué-Pepe-Carvajal
-------------Casemiro-------------
----------Modric-Iniesta----------
----Messi-Suarez-Ronaldo----

Navas
Carvajal ramos mazcherano marcelo
Modric busquets iniesta
Messi. Suarez. Ronaldo

Easiest choice.

Navas
Carvajal - Mascherano - Pepe - Marcelo
Modric - Busquets - Iniesta
Messi - Suarez - Ronaldo

Navas
Carvajal - Ramos - Mascherano - Marcelo
Busquets - Modric - Iniesta
Messi - Suarez - Ronaldo

This is my team:

Carvajal - Ramos - Masherano - Marcelo
Modric - Iniesta - Busquets
Messi - Bale - Neymar
