Nani > Cerci. I don't rate Cerci, and don't see the point in wasting money on him. Nani has actually, on occasion, proven to be a WC player. I have a feeling Conte can rejuvenate him, make him enjoy his football again. Case in point: Tevez. Menez is incredibly inconsistent, but for free, he is a bargain. I like Ocampos, but would Monaco really be willing to let him go? They are the other moneybags team in France.
I am all for investing in Italian players (Cerri and Mauri from Parma for example), but they need to be quality acquisitions. We must also look beyond the borders and recruit young, promising talent to have a well rounded/balanced team.
