Former Atalanta coach Angelo Gregucci says Juventus cannot afford to sell Matthijs de Ligt on the cheap.

The Holland defender is wanted by Chelsea and is eager to see the move happen.

Gregucci told TMW: "If Juventus does not sell De Ligt for more than 80 million (euros), in my opinion it makes a huge mistake.

"The market is at a standstill but if you have noticed that regarding the central defenders it is very active, because they have become a very rare commodity.

"I was saying it is a huge mistake because you will never find a 1999 with the Dutch's experience.

"(Kalidou) Koulibaly is a top defender but he is older. The really rich offers actually come from England more than from Italy."
