Given Zapatas age and outrunning contract and Musacchio being somewhere between mediocre and decently okay, I think we should start Caldara with Romagnoli the moment he's fit enough to start games.
Zapata: Best season with us ever and suited very well as Romas partner. That said he's not the future. And injured anyway until only God knows.
Musacchio: Isn't that good in the air and has played this season more like Zapata once used to, meaning two good games followed by a brainfart game. He's definitely not going to be our future as well.
Caldara: Very good in the air, young and full of potential. Definitely going to be Italys future CB alongside Roma and brought here for 35ish millions or so to form that partnership already now. We should close our eyes and just start him asap.
Yeah I'm serious. I hope Rino is brave enough to throw Caldara into the mix once he's fully recovered.
