I remember writing last season that we should try playing messi on the left and someone else has the false 9, against madrid has it will render Jose's plans of a defensive 3 with Alonso/Pepe basically man marking Messi ineffective and it seems kas front 3 is right, but what I don't want to see is Villa in that front 3, we need someone like him/pedro for their pressing.
if that's indeed the attacking 3, I am a bit worried, but lets see if it will work, messi playing on the left will pin back Marcelo and require pepe or one of the dmeds to cover him, which will open up more space in the middle, cesc will play a big part in this game.
