Chelsea, Manchester United, Arsenal, Real Madrid and Liverpool have all been long term admirers of the Napoli star.
Napoli set to demand £105m for Kalidou Koulibaly.
The Italian giants have reportedly decided that they will only sell Kalidou Koulibaly for 105m.
Koulibaly has established himself as one of the most highly-regarded defenders in Serie A, with eight goals being scored in 122 appearances across four seasons.
Arsenal were last club to have enquired about the player and according to RAI Sport they are willing to offer huge bids.
But they may have to fight off competition from the likes of Chelsea, Manchester United, Real Madrid and Liverpool.
The report says that Napoli have no intention of parting ways with the 26-year-old, which has led to the Italian giants only being open to a world-record approach for a defender.
