Wolverhampton Wanderers are in talks with Max Kilman to extend his contract with the club, according to the Telegraph.
Wolves recently rejected a £30 million bid from Napoli for the 26-year-old. Manager Julen Lopetegui is a fan of the centre-back and wants him to sign a new deal.
The new deal is reportedly lucrative and will keep him at the club long-term.
However, the Serie A champions will make a new offer for him in the coming days. They see him as the successor to Kim Min-Jae, who is on his way to Bundesliga giants Bayern Munich.
Kilman is a solid defender. He has all the tools to take his game to the next level in Naples. The Englishman helped Wolves keep 11 clean sheets in 37 league appearances last season.
He won 67% of his ground and 59% of his aerial duels and records excellent progressive passing and carrying numbers.
It is clear why Wolves are reluctant to sell the defender despite needing the money to avoid breaking Financial Fair Play (FFP) rules.
Wolves have already sold midfielder captain Ruben Neves to Saudi Arabian club Al-Hilal for a club record £47m.
They have also sold Nathan Collins to Brentford for £23m, and Conor Coady has joined Leicester City for £7.5m.
Napoli are serious about Kilman but must raise their offer to persuade Wolves to consider a sale.
The centre-back also has interest from Chelsea and Tottenham Hotspur, although it is unclear if either club will enter the transfer race.
Chelsea already have two left-footed central defenders on their books, but Spurs need to revamp their defence after conceding 63 goals in the Premier League last season.
Kilman is happy with Wolves. He will not look to push for a move knowing he is a top candidate to replace Neves as captain.
