With all respect but this lineup would be exposed as hell defensively. Messi can't play as CM in 3 man midfield, forget about that.
You are right. That is actually the problem; however, we should still try to find a way for the new version of Messi. I do believe that the new Messi is going to be way more entertaining and enjoyable to watch if he is surrounded by the right players, once it clicks, we are going to witness something totally different for even more years.
Just going to Ronaldo to illustrate how his new position made him alive again. Zidane knew that he just cannot dribble anymore, he is still fast, but not so good one on one. Moving him deeper and letting him take care of the finale touch was brilliant. However, Madrid had to play in a different formation. They currently play 41212 narrow
------------------Ronaldo---Benzema
--------------------------Isco
----------Kroos-------------------------- Modric
-------------------------Casemiro
Marcelo ----------Ramos--------- Varane---------- Carvajal
When they are attacking, Marcelo and Carvajal play as LW & RW:
-------------------Ronaldo---Benzema
Marcelo-----------------------------------------------Carvajal
--------------------------Isco
----------Kroos-------------------------- Modric
-------------------------Casemiro
---------Ramos-------------------------Varane
However, I do not think we can play 41212 because we do not have good fullbacks and also because we do not have strikers who can finish the crosses. In addition, we play a little bit different and our midfielders are not great to play in such formations yet. We still should try it, but I just do not enjoy playing without actual wingers.
Messi's visions is absolutely amazing and his passes are lethal and that just never gets old. With the right players we could keep him for what , 5 more years? Saying Messi cannot play in a two player midfield would not solve the broken unbalanced right side. We are going to have the same issue, he is going to drop deep and our team is going to be a bit unorganized.
