Lazio coach Maurizio Sarri has warned new arrival Luca Pellegrini.
The fullback has signed from Juventus, where Sarri had a short spell working with him.
He said, “I didn't coach him for too long. I remember he sustained an injury in July and then I had a problem in August, so we hadn't met many times on the pitch," noted Sarri.
“He is a natural left-footed defender, but I delivered him the bad news. A defender arriving on January 31 has never become a regular starter with me. I did it with midfielders and strikers, but never with defenders. It's not the players' fault, but mine.
"I play with a different defensive style, keeping a high line, so it's not easy."
