Federico Fazio: 'Sampaoli told us not to depend on Messi'
However, Roma and Argentina defender acknowledges that it's hard to do.
"In the national side, we have a system that I personally like where we press high and try to recover the ball quickly and I like that.
"In Sampaoli's system, we are asked not to depend on Messi but it is inevitable sometimes because he's the best in the world.
"Leo opens the game up and turns things whenever he touches the ball and even when he doesn't. He's been the best in the world for years."
If not Messi, then who?
