Napoli have accepted that they may have to sell star defender Kim Min-jae this summer despite long insisting that he will stay at the club, 90min understands.

The South Korea international has announced himself as one of the world's leading centre-backs since his move to Serie A from Fenerbahce last summer, and is known to be of interest to Manchester United, Liverpool and a number of other leading clubs.

The 26-year-old has played a key role in helping Napoli win their first Scudetto since 1990, and the Partenopei have spent much of the year trying to tie Kim and winger Khvicha Kvaratskhelia down to new and improved deals, believing that striker Victor Osimhen would be the only high-profile departure in the summer.
