Lazio coach Maurizio Sarri sung the praises of Nicol Casale after victory over Sampdoria.
The young defender was again impressive for Monday night's win.
Sarri said afterwards: "Let's not talk about it otherwise they'll call him up for the national team (laugh)...
"He still needs a little work, but the path is the right one.
"He has technique, physique and acceleration. In the first few months he struggled to get into the mechanisms, but now the situation has changed."
