Liverpool are set to make a big money bid for Napoli centre-back Kalidou Koulibaly.

That is the opinion of market intermediary Vincenzo Morabito.

The official, who works on transfers, believes the 29-year-old centre-back is the man Liverpool see as the ideal partner for Virgil Van Dijk next season.

Koulibaly, who has been linked to Premier League clubs for years, may finally be ready to leave Naples.

"I believe that for Koulibaly it could be a good year to leave," Morabito told Calcio Mercato.

"Liverpool will go heavily and, at the moment, I think there is a big possibility that Koulibaly will be able to leave Napoli."
