Napoli boss Maurizio Sarri is delighted with their swoop for Empoli midfielder Mirko Valdifiori.

Valdifiori was a key figure in Sarri's Empoli and will have his medical for Napoli on Saturday, having agreed a €5.5m move.

Sarri said, “He is decisive in his role, a player with incredible speed of thought and movement of the ball. In the space of three years he has become one of the best midfielders in Italy.

“He has technical and mental quality which is beyond the norm. Mother nature gave him this unique speed of thought."
