Former Tottenham assistant coach Cristian Stellini has sung the praises of Tanguy Ndombele.
The Spurs midfielder helped Napoli to the Scudetto while on-loan last season.
Stellini said: "He's a pure talent. On a technical level, and in terms of explosive strength, he's a very pure talent. Maybe he needs to feel pampered too much. He'll have to mature from a character point of view.
"If you follow him he demonstrates that he can guarantee a certain type of response. Otherwise, left to himself, he tends to get lost.
"By now, he is 25 years old, he is no longer young and it is necessary to follow a certain type of path."
