Agent Andrea D'Amico believes Juventus should sell Matthijs de Ligt.

The Holland defender is a target for Chelsea.

D'Amico told Tuttosport: "The price of De Ligt is 100 million.

"If I were in Juve for that amount, I would come and reposition myself by buying two players who cost less.

"(Napoli defender Kalidou) Koulibaly, who could sign for a new club in January, cannot be worth high figures."
