Napoli head coach Carlo Ancelotti has heaped praise on Napoli defender Kalidou Koulibaly as the best centre-back in the world and is worth €150million.
Manchester united has been linked with a potential move for the center back but Ancelotti warned off potential suitors.
The Senegal international has been at the Stadio San Paolo since signing from Genk in 2014, and has developed himself as one of the best defenders in Seria A
According to Ancelotti:
"The best centre-back in the world? I would say so," he told Tuttosport. "And he can still improve. He is worth €150m and he is not available for transfer.
"Koulibaly’s contract expires in 2023, in 2021 there's a €150m clause but Napoli do not need to sell, the president [Aurelio De Laurentiis] does not want to sell and the question doesn't come up."
Ancelotti also said he is happy to be runners-up:
"Second place is not a discredit to us, it’s a credit to Juventus, who are going along at an exceptional pace," added the former Chelsea and Real Madrid coach.
"If they [Juve] continue like this, they can finish with 100 points" he said.
