Ideally not a fan of Caceres at times shaky positioning, or instinctively choosing to press too eagerly at timesf, but I would still deffo start him over Marrone, trust him more for sure (in overall a solid enough choice). Especially in games we are likely to be tested more. Marrone as a defender I simply dont trust, for obvious reasons not just natural in that role, his iffy positioning plus generally lacks any aggression, would be reluctant even more when its a game where we are missing 3 out of our 5 regular options, not because he is needed in midfield, but because he is likely to be exposed more without same reliable covering. Not to mention the reason he is played in Bonucci role is supposed to be for giving similar passing approach, while in his last two games, he was just making quarterback longballs to nowhere all the time.
Should defenitely allways play when Barza or Giorgio are absent, over players who arent CBs like Marrone and Peluso.
