The president of the Serie A club said he'd have paid £30m for the defender and suggested English wealth was responsible for high fees for players
Napoli president Aurelio de Laurentiis has scoffed at the fee Manchester United paid for Harry Maguire and said a player on the books at his club was worth three times what United paid for the England international.
Maguire moved to Old Trafford from Leicester City for £80 million ($97m), a world-record price for a defender.
De Laurentiis believes that is far too high for a player of his calibre and suggested that Kalidou Koulibaly could command £250 million ($303m) if here were to be sold.
