Former AC Milan striker Giuseppe Galderisi says Matteo Guendouzi still has much to do at Lazio.
Galderisi was asked if Guendouzi can replace Sergej Milinkovic-Savic since he left last summer.
But he told TMW Radio: "In short, there is still a big difference.
"He is doing well, but Lazio alternates good things with less good ones.
"(Maurizio) Sarri knows what he has to do, he knows how to adapt his way of seeing football to the characteristics of the men he has."
