Don't forget Martin "Beckenbauer" Caceres.
I'm not that critical on Caceres. I'm not assured when he plays as I think he's prone to mistakes. But when the alternative is Peluso, I'd rather play Caceres.
Marrone shouldn't play CB. I've seen enough to say he isn't suited to that role, he doesn't offer defensive stability.
But DC, DC, is just knowing you'll gift a goal to the opposition. zero agression, IQ or stability.
