Chelsea have reportedly told Napoli that they will not increase their latest offer for defender Kalidou Koulibaly.
The Blues have been heavily linked with the 25-year-old over the past month, and reportedly offered a club-record fee of £60m for his services last week.
Chelsea have already seen a string of bids for the player turned down, but The Telegraph reports that their latest offer will be their final one.
Napoli are reluctant to sell the Senegal international, although the player himself is understood to be keen on a move to Stamford Bridge.
Chelsea have already begun looking at alternative options should they be priced out of a move for Koulibaly, with Torino's Nikola Maksimovic one of the names linked to the club.
