I don't have much experience in football but my grandfather owned the football club in the town where I was born and he
also was a manager at some point. Let me use my "inherited" skills and elaborate
I love to control the game so I will pick a 4-3-3 formation. Messi (my choice) would play as a RW. I want a left foot Striker / Center Forward who
from time to time would switch position with Messi
The RB and RCM (right back and right central midfielder) must come to ball and support that change. Basically Messi and the CF would pass to those guys
and make the movement by support. Imagine one goes one way, the other goes the other way but through passes. Sometimes this can create lot of space
for the RB or, it can attract the other side of the opposition defence allowing long passes to the LW.
Cristiano Ronaldo has great abilities but I don't see him in this crazy switch with the Striker. Ronaldo needs his space and plays as he wants using his abilities as he
knows. When he aged he changed his football style to fit his abilities. Also I'm not a fan of crossing so I would not be using Ronaldo's heading abilities which is a stupid
idea if you have Cristiano in the game.
Because if someone can be followed as an Ideal, then that person is Lionel Messi.
