We must not lose this game. A draw would do.
I would field this 11:
--------------Ter Stegen--------------
Semedo---Pique---Vermaelen---Alba
---------------Busquets---------------
-------Paulinho------Iniesta----------
Roberto------Messi------Suarez------
Why? Roberto looked amazing in the last few games attacking-wise, so I would use him as a RW. Defenisvely, he and Semedo could shut RM's left side down and forcing Marcelo to stay back. I would go with Paulinho instead of Rakitić, because he can bully Modrić and Kroos off the ball. And I would still play Verminator, because Mascherano hasn't played a minute since he has been injured.
But the Valverde special will probably be:
--------------Ter Stegen--------------
Roberto---Pique---Vermaelen---Alba
---------------Busquets---------------
---------Rakitić------Iniesta----------
---------------Paulinho---------------
--------Messi------------Suarez------
I hope that Valverde realises that Paulinho's worst games this season have been, when he has played as a CAM in 4-4-2 diamond. Whenever he has played as a CM, he looked more involved in the game. He also must remember the supercopa, the 1st leg, where the Marcelo vs. Robeto matchup didn't work particulary well for us.
